So I've done a bit of searching and I still find my self lost as to what should be the next logical step to get more power out of my 2005 r53, so many people have told me so many options, the car currently has a DDM CAI, %15 sc pulley, colder plugs, and a borla cat back, what would be my next logical step, I looked into a flash tune for the Ecu but RMW told me they wouldn't do it unless I had a cam, which I am not looking to upgrade
Power wise, if you're not looking to do a cam, you could put a new header on it, bigger injectors, and tune. If RMW won't tune it for you without a cam (which sounds really strange to me) then I'm sure someone will. Maybe look into a byketronic tune?
You've done all the easy power upgrades except a tune, so to me that seems like the next logical step.

I'm really not opposed to a tune but they just kept talking about their street cam when I was trying to email them, if I went to a smaller pulley, 17 or 19 and bigger injectors and s tune think I could get anything worth while out of it?
ECU tune is always the last mod we recommend after doing all your hard parts as the tune will be used to pull everything together and be done for how the car is that day so you won't want to make changes if you get a full dyno tune. We do offer a basic tune that allows you to continue to do mods without fear of running lean or causing problems, but it's not going to net you a bunch of power as it's designed for safety and ability to continue adding mods. https://www.waymotorworks.com/wmw-ec...-cooper-s.html
If I would you the next mod if you haven't done it would be an ATI damper, not only will it be a little lighter and give you a slight bump on boost, but these are so common to fail this would also be considered a maint item as it would prevent you from having to worry about the stock one failing in the future like they all do.
But our Way Mild Street cam would be a nice bang for the buck and the next mod I would recommend. https://www.waymotorworks.com/way-mi...t-r52-r53.html
I know you said you didn't want a cam, but it is idealy the best next mod.
Otherwise adding a Quaife LSD would be a great mod as it will allow you to get all the power you currently have to the ground, but will cost more and take more time.

Hi cirone! We have a step-by-step performance upgrade guide you can use as a reference for free:
I wouldn't recommend a 19% pulley, they spin too fast, make a ton of heat, wear belts rather quickly, and put the M45 out of efficiency.
If you're looking to go with a smaller SC pulley I would recommend 17% max, and a 0% crank pulley.
More boost doesn't always equate to more power, flow dynamics will though. So added cam duration, quality header, a quality head, more fuel, a tune is where you go from here, and it can get quite expensive quite quickly, so what you expect from the car is the question in need of answering.
Personally I have the same engine mods on my car with the addition of 380 injectors, but the suspension has been gone through; sway bars front and rear, lowering springs, Koni yellows, poly bushings here there and everywhere, brakes, sticky tires, and those mods are what really woke the car up to me. The performance gains from the suspension work was worth more to me than any of the performance engine mods.
If you decide to start tuning the car, do so with the proper monitoring; boost gauge and wideband O2. It makes life easier to have a loader, or software to do your own file loading and logging so either a Mynes setup or the RMW loader would be beneficial to keep your downtime to a minimum.

My car has all the same suspension upgrades as yours, so I'm thinking a %17 pulley and injectors and a tune

I think you have done all of the "cost effective" mods that most people do. Anything more is going to start costing you some big money. Big Valve Head, Cam, Custom Tune....$$$$$
I pretty much stopped with engine mods after I did all of the basics like you did, I'm concentrating on brakes and suspension mods now. I can't see spending thousands of dollars more just to squeeze out another 20-25hp. To me it's just not worth it...especially for a daily driver.
Good point, IQ. Extra HP doesn't work real well if you can't transfer it to the pavement and be able to stop, which is where suspension and brake upgrades come into play.
These performance upgrade and R53 guides might help. Please let us know if you have any questions:
what do y'all think about an upgraded bypass valve?
ive seen good things about it and not much bad, but you guys seem to know whats up when it comes to upgrades.
worth it? been thinking about getting one here soon
I don't recommend the aftermarket bypass valves. If you have a proper working valve you are fine. It's not a bad idea to inspect it and adjust the stop to make sure it is closing all the way.
I run the stock bypass valve on my street car and on my race car.

I agree.....the reason I went with a DT bypass valve was because the spring in the stock BPV broke. The only real difference I noticed with the DT BPV was the boost comes in a little sooner, and I lost some mpg. If your stock one isn't broke ...don't mess with it.
