V2.0 runs great.. but i have 16psi Spike at 6500 Rpm..

So ive been messing with my torque settings on the 12-26 map which works on my car..

I notice if you bring the boost on to quick say like 14psi at 4k rpm, the power up top just dies out.. So lowered those values and aimed for the 15psi at 5500rpm which is suggested and it works out great..

Only problem is, as Im tapering to around 13-11 psi to redline, there is a 16psi spike for abouta 300 rpm jump sometimes 17psi, at 6500 rpm.. My car acts funny,throws little limps and I already thru a Massive Limp mode that needed to be corrected at the dealer..

Im playing with the torque value at this level and seeing if i can bring it down.. so far it seems possible, but its quite awkward everything stays even and then just Boom it flys up, while im still on the gas..

Otherwise ill say that my car is FAST.. I raced a RS4 on the Autobahn yesterday and was pulling away from him.. So funny to see peoples reaction as they have no clue how a 3 series is spanking them..

RS4 and SL55/anything 63 are such satisfying kills, enjoy, be safe~
