Looking at the dyno graph again, I can only presume it's wheel spin, wasn't there for the runs, had to be at work today, but day to day driving there certainly isn't any noticeable turbo lag.
Regarding peak power, I'm not sure what peak PSI the Procede tune aims for normally but I'm pretty sure if I had put the boost limit up above 14PSI it would have hit 400 quite easily but I rather run the car day to day on a lower boost target, and 380bhp is hardly a 'low' output
.
Pretty happy with the car, the only other upgrade I'm seriously considering is RB turbos for when the OEM turbos eventually go. In sort the N54 unit in the 335i is great
