i raced my buddies 335is with no tune but fmic/dci all the time before. At the time i only had the jb3 stage 1 at 2.75 and injen intake, I always lost by about 1 car lengh. However when we did 60-130 runs i always caught up at the end of 4th gear and started pulling on him slightly but it was almost always neck to neck unless he misshifted (6 mt). a stock 335is dynos around 315 whp, and im pretty sure my friend with his dci and fmic he was about 335-340 whp. His car was extremely quick (over boost function) Manual car's just feel faster lol.

Smaller turbo gives issue on the top end.

IMO gain can be make on the mid range (mainly torque) with better tune, better cooling, better fuelling. Meth can also help the top end. No ressource/time were spent working on this.

On the Vag 2.0T it was the same game for the first 3-4 years than came upgraded aftermarket fuel pump, injectors, at first 230whp/260wtq was the limit at 15-16 PSI, higher PSI was impossible because AFR was too lean. Than came the fueling solution and now this small 2.0l Ko3 turbo can run 18-19 psi on mid range and make 270whp and 350-360 wtq without upgraded turbo.... We have a 3.0l 6 cylinder, not a 2.0l 4 cyl....

My point was that I felt my car faster with jb4 and no Dp, charge pipe, or intake. I thought Dp alone made a difference but I just don't feel it. Dyno next week.

It does not make a huge difference, but does reduce back pressure a lot, reducing stress on the turbo by a fair amounts.

Tell us something we don't know. My opinion of the N55 will change once I hit 12.5 in two weeks.

Ditto mate.. I just hope these 335Xi guys who are losing to N54's aren't comparing them to non X models. As it goes without saying that it's going to be slower (extra weight and transmission losses), just look at the trap speed differences between the 2..
I recently had several runs with a 335i N54 DCT E92 with JB4 at our local track in my flash tune only 135i DCT. I wasn't sure what to expect tbh, especially after reading some of these threads, but...








I know my 135i will be slightly lighter, but the way some of the N55 haters go on I should of got mothered..

My car dynoed 18 whp over stock with a 4'' dp so that's not the case.
