reflash dyno results plus brief mod review
I recently got my 2016 MCS back from adding a bunch of mods and thought I'd share my thoughts plus some dyno numbers. When I bought the car it already had a JCW pro exhaust with JCW tune, racechip gts and 18" OZ wheels. I added the following upgrades. Needless to say the combination of the following mods really transformed the car. It's funny because I tried to buy a car that was already modified to my liking but of course when I saw the aftermarket support for this platform, I couldn't resist trying to improve what I felt were the weak points of the car, mostly the lack of an LSD and some negative camber.
https://drive.google.com/open?id=1WD...RXNVNttd3GaRWR
1. Bytetronik stage 1.5 tune (replaced racechip)
2. Wavetrac LSD (with new oem clutch)
3. KW street comfort coils with K-mac camber plates
4. Eventuri intake
5. Wagner intercooler
6. Forge short shifter with JCW shift ****
7. Michelin pilot sport 4S 225 tires
1. First the difference between the tune from Bytetronik vs the JCW tune with a piggy back is quite noticeable. Unfortunately I did not dyno the car before the latest round of mods and reflash but feels like at least a nice 15-20% bump in power from what I had previously (I know butt dyno doesn't mean much). The bangs and pops with the exhaust open are now much more prominent. The sounds in mid mode are now similar to the bangs and pops in sport mode before the reflash. In sport mode it's now a whole different level of sounds, almost comical and makes me laugh like a kid. I can only imagine with a downpipe and stage 2 tune. Luckily my wife still hasn't caught on to the exhaust or driving modes, or she'd never let me open it. Before the reflash the car would only bang and pop in sport mode on decel at certain rpm's with a certain amount of throttle input, normally in the middle of the rpm range. Now in sport mode the car bangs and pops every time you let off the throttle and on every downshift, hasn't got annoying yet, love it! The power still feels like it falls off a bit above 6K rpm but there was definitley an improvement there as well. The car has a tremendous amount of torque in the low-mid range and that's what's most noticeable from the dyno pulls. Car only made 222 WHP a little bit lower than I was hoping for but it also made 310 ft/lbs of torque to the wheels from 2700 rpm! That number was higher than I expected, especially without a downpipe and stage 2 tune. I know a dyno is just a tool and without before and after numbers the results are kind of irrelevant but I thought I'd share anyway.
2. The LSD was the number one thing I felt like the car was missing from the factory and is what got me with the mod bug to begin with, the rest of it just kind of snowballed along with it. I would say this is the least noticeable upgrade for daily driving situations and I have yet to get to autoX to really put it to the test but here are my thoughts based on the canyon driving I've done so far. You are able to get on power much sooner exiting turns and the car seems to push much less. Changing tires and suspension obviously helped this as well. There is much less torque steer when accelerating in a straight line but still more than I'd like. I will have to report back after my first cone dodging session but overall I am pleased so far!
3. I was honestly fairly content with the factory DDC dampers for daily driving. I felt like with some camber plates and a decent alignment there was room for improvement. But when I discovered one of my shocks was leaking fluid and I looked at the cost of replacing the DDC dampers I figured it was a good excuse for a KW upgrade. The springs could definitley be stiffer but I knew this when I opted for the street comforts. I also wanted a minimal drop for decent clearance and not scraping everywhere. In order to achieve the alignment specs I was after a 1 inch drop was needed front and rear. This is fine by me but I'm glad it's not any lower and I for sure have to be a bit more mindful pulling in and out of steep driveways. I'm too old for a really low street car! While the spring rates could certainly be higher for autoX I think it will be fine since I plan on staying with a 300 treadwear tire. Ride is only slightly harsher than stock, I can run over bumps and reflectors on the median without much harshness. Due to the camber plates there is definitley some added NVH when you go over really rough broken pavement but that's the trade off for having the car turn in the way it should.
4. Eventuri intake, this one was a guilty pleasure. When I saw they offered a plastic version for a lesser price I was able to justify it, barely... I guess I'm a sucker for making a fake vent into a real vent and when that's an option I'll normally take it. The carbon hood scoop definitley looks cool and there is a slight increase in the turbo flutter but most of the sound is outside the car and you only get to enjoy a bit of it from inside the cabin that is quickly overshadowed by the bangs and pops from the exhaust. My guess is if you added the hard boost pipes as well you'd get a big increase in turbo sounds inside the cabin? This is my first turbo car and I find myself constantly on and off the throttle just to get the feeling of the little turbo spooling up, very satisfying. Maybe when my car is due for smog I'll try to do some dyno pulls with and without the intake to see if the high price tag is justified. It definitley adds a cool factor.
5. Wagner intercooler, another one that would be nice to have before and after dyno numbers but it did seem to be doing it's job between pulls. I did several pulls in 4th gear and after each one coolant temps shot up to 220 but would quickly go back down to 200. I can't say for sure if this was helped by the larger intercooler but i'd like to think so. This reminded me how happy I am that I've decided to only daily and autoX the car and not track it, just eliminates so many of the headaches you run into trying to track a street car. Namely cooling and brakes.
6. Forge short shifter and JCW ****. This simple mod probably brings me the most joy on a daily basis. I know others on here might prefer different short shifters but I was very pleased with the results from this one. Throws are probably only 20-25% shorter but shifting effort is increased just the right amount with the right level of notchiness without making shifts difficult or laborsome. I found the factory shifter to be very vague and mushy. To the point to where sometimes I had trouble telling what gear I was in. The biggest issue was that I'd occasionally put the car in 3rd from a stop instead of 1st, then I would kill it and feel like a fool because the car doesn't make that much torque to where you can leave from a stop in 3rd (although it does make plenty!). This hasn't happened to me once since adding the short shifter, very direct feeling with the shifter now and the JCW **** made it feel much more quality. I've also had a lot of negative experiences with short shifters in the past with problems like rattling that have almost turned me off to aftermarket short shifters altogether but I'm glad I gave this one a try.
7. Michelin Pilot Sport 4S tires. I've always been a huge fan of Michelin's as a street tire, not so much as a track tire after feeling like I've wasted money on Cup 2's in the past but as far as street tires they are the best in the business. Now I can't say I normally buy them because I tend to go through tires fairly quickly on the street so it's hard to justify the cost. I normally only get 5-10K street miles on a set of tires with lots of hard canyon driving. Michelin is the only tire company I'm aware of that stands behind their product and their warranty. Years ago when I bought my BRZ it came with Michelin tires that I proceeded to blow threw in 5-7K street miles. I was able to file a warranty claim with Michelin and get a replacement set of tires for $100. Now the wear has to be even front to wear and obviously it can't be track use but I was loving their warranty while it lasted. They ended up cutting me off after about my 4th set of pilot super sports from them but this was years ago so I may try again! They also replaced my Cup 2 tires under warranty when they started chunking like a cheap street tire after 2 track days. I don't know of any other tire manufacturer that would do this. I use to kind of make fun of "pilot super sports" and say they should be called pilot semi sports because while they are a great street tire the grip level is just way off the top tier 200 TW tires. This new pilot sport 4S tire seems like a nice evolution of the super sport that bridges the gap and is a bit closer to the grip levels of the latest and greatest 200 TW tires. Again cannot wait to try them out at my local autoX to get a more informed opinion.
End of story is this platform responds great to mods! Have always been an NA guy but there is no denying the joys and efficiency of a turbo. Being able to gain over 100 ft/lbs of torque to the wheels with relative ease is a beautiful thing. I might be coming around to these little turbocharged engines. I think it definitley helps that the MINI comes with a lot of character off the showroom floor. When you add a generic 2L turbo engine to a crossover with no character the results are of course a boring a car. I will drive this MINI till the engine blows up or the wheels fall off and enjoy every minute of it, amen!

Wow, nice write up 
And thank you for supporting Bytetronik! Based on our dyno testing results on a Mustang Dyno, a stock F56-S lay down 170 to 180 WHP. And that's peak HP. The difference between an ECU tune and a piggyback is the power delivery (HP and torque would come on a little bit quicker with the reflash. Happy motoring!
