RPM Tune Review/Info

Car and setup:
2014 Roadster S-Auto
JMTC S42 Turbo
Wagner Competition IC
Resonator delete with hard charge pipes
K&N Dry Filter
modded stock intake
2.5 catless down pipe (eBay special)
Stock exhaust
92 Octane (US)
1 range colder NGK plugs

I drove up to Canada to get my R59 flashed and get a before/after Dyno, pulls taken roughly 80 minutes apart, car was never unstrapped. I am a paying customer with zero financial interest in RPM.

Point 1:. It's a mustang Dyno with a dynojet correction factor applied, don't compare numbers to dynojet numbers.

Point 2: .My car baseline was 7whp short of a saved stock JCW baseline they'd done on the same dyno and my R59 made 3lb-ft more torque than the same JCW.

Lorenzo was awesome! He's very meticulous, ensuring all codes were gone before I left for the day. He polite, thorough, knowledgeable, and a mini owner and enthusiast himself. He brought his beautiful Connaught Green 2010 JCW Championship Edition out, a very limited edition one (hint-it got dynoed too).

My tune options were:
More pops and bangs (ensure you want this if you ask for it, they're both louder, more numerous, and easier to trigger)
Linear throttle in non-sport mode
1.35 bar boost

I got a good 200 mile drive home to get to know the new setup. The car is super smooth, no hiccups, no jerks, no slow shifting, no codes, no overboost, no-anything unexpected. Runs smoother than pre-tune.

Logging peak boost a few times I saw 20.2, 20.5, 21.1, 20.7... I'd say that's pretty consistent across various conditions. Some where kickdown passing, some where single gear flooring it, some were slow roll ins. The spool time is MUCH faster now, the pull is much harder, and the engine runs better (smoother, more responsive).

I'm super happy I went to RPM and not another vendor, because this is literally as drama free as possible. So enough chit chat here's the before/after:

178whp/198lb-ft stock tune
229whp/262lb-ft RPM tune
gains of +51whp/+64lb-ft
AFRs were checked on the dyno and were exactly where they target, so all is well.

Video Below:
Apologies for the FILTHY car, all the roads have mass amounts of salt/sand and it was drizzling on my trip up.

I believe this is considered a stage 3, two cavaets to remember:
1- This is an Auto so a little more loss than the 6MT.
2- Boost level is not terribly high, and there is no ethanol or meth involved, meaning a methed tune with more boost will be even stronger....

On to the bonus bits:

We tested a prototype air intake after doing that pull and with no other changes the car gained 7whp and 9lb-ft for peaks, but there were 5whp gained pretty much everywhere over 2200 RPM, he's got a winning design when it's released! Anyone who beats the "there's no power to be made pre-turbo" drum is flat out wrong, sorry guys, I watched two clamps come off, intake fitted (pre-maf section only btw) and gained 7 and 9 on top of what's above.

The extra bit was seeing his built motor JCW make 270whp with a stock JCW turbo using a stage 2 tune, quite impressive, and I think the highest stock Turbo Dyno I've seen yet.

TLDR: RPM fing rocks, skip all others and go directly to
RPM.

Perfect timing on this review - I'm waiting for my Akrapovic downpipe to show up for my R58S, and the ECU will be off to visit Lorenzo for a stage 1 tune.

I'm glad everything written so far about RPM Tune is positive. It makes me feel more confident picking Lorenzo and RPM over Manic.

Keep us all in the loop with updates, please!

(I may have to bother Lorenzo for more info on his intake. Very curious!)

A couple days on, no issues. Finally got a good data log session.


Idle is definitely smoother. My car doesn't have the downpipe heatshield fitted, so the manifold shield sometimes tapped against the aftermarket turbo heatshield making a small rattle at warm idle. It now doesn't do the tapping, so not judging by feel, judging by lack of vibration induced noise, its a bit smoother.
Full boost ignition timing seems conservative, a good thing imho if you have any level of mechanical sympathy for your engine. Without knowing exactly what the cams are doing, one cannot really say if it's conservative or not.
Lights off DSC blinking in 1st...2nd...and 3rd at full power, no big increase in torque steer when it does actually grip (thanks automatic trans). There's actually a reason to leave DSC on now haha.

I am a HUGE fan of linear throttle mode. I wasn't sold on it before, but, with how fast the turbo spools when tuned, having a linear throttle instead of the progressive action is nice. Trying to hit say 10psi or 12psi for moderate acceleration is very hard with the progressive action, it wants to go straight to full power, with linear you can actually meter in power, while I kind of wish I had linear on non-sport and sport, having both is still fun because the dynamics change drastically when pressing sport now :P

Gas mileage... shockingly, is better (when I'm not playing). To some that may not be a shock, usually well tuned motors do get better mileage, but I'm getting about 35 cruising at 70mph on flat freeway.

Where the power is most useful for me, is the drive off corners where I'm lateral grip limited, for example, say I have to drop to 60 mph for a corner or start drifting to the outside of the turn, once I apex, the pull is immense now and keeps the car right at the grip limit until the turn completes, previously, there was not quite enough torque to drive off the corner at the limit. The result was previously I was often overdriving a corner to maintain speed since I knew I couldn't get it back post-apex, now it's much more intuitive to follow a traditional racing line.

I live in Richmond, and had my sons car done, difference is incredible. He's running a JCW turbo, bigger intercooler, silicone charge pipes, cold air intake, alta 3" exhaust, 100 cell downpipe, lightened flywheel/clutch, Howerton Methanol Injection. Great job done by Lorenzo, and no issues at all. Seamless power, good idle, no overboost etc. stage 3 running 22psi. Haven't had it dynoed yet but its slick and quick!! mine is next!

I have these same mods on my car, except the lightened flywheel/clutch. SO I'm very curious about what this adds/does differently than the stock oem flywheel & clutch, and is it worth getting?

Claviger: do you think you're done with modding since you seem pretty happy with the results from your RPM tune, just wondering if you have some other mod to do next?

A few thousand miles later, no issues at all. I am done with power mods at this point, no point in more power until the motor has forged internals.

The car is quick enough to be fun and a handful if you're not paying attention when you boot it.

The weather has gone from 30s to 70s and still floats between 20.1 psi and 21.0 psi so it's consistent and not overboosting.

All future mods will be suspension.

The engine definitely builds revs quicker with the lighter flywheel, slightly more rattle from transmission gear lash when idling in neutral. Just had my car tuned b Lorenzo, big difference, just waiting for my jcw turbo to arrive, should be this week, then its going to really light up!!

Could someone clarify the linear throttle option for me please? I don't quite understand the difference between linear and progressive throttle response.

Thanks kindly!
