I also came from heavily modded Suby, I had a stage 3 externally gated 2011 WRX. I had it putting down 375AWHP/380TQ before returning to stock and selling for a 135i.
Anyway, if you think you're car is feeling boosty, like not linear at all, you should think about getting rid of stock charge pipe and intercooler as well as all the crappy fittings/couplings in between. if you look at the stuff, it is cheap plastic/thin rubber not capable of holding high boost levels.
Sounds like you're off to a fine start though. You should take your Cobb somewhere where you can get it pro-tuned, I have found the custom map to be far superior to the OTS Cobb stuff, way less throttle sensitive and not boosty feeling.
Good luck

Is it me or is it the DTC, funky limited slip, RWD, or inadequate plumbing that makes it seem so rough in 2nd/3rd gear pulls? My only other boosted car was an STI and it seemed much more capable of handling added psi and put down power much smoother even factoring in the AWD.
Looking to see if my experience is typical, and your opinions.
By the way, my '07 STI with meth, down pipe, axle back, CAI, bigger intercooler, pro tune, under driven accessories and Cobb couldn't hold a candle to the 135 with the meager mods listed above. Very impressive from someone new to the 135. Thanks in advance.
