I mean ecu is full of filters,limiters,dashpots used to smooth street driving. On racecar every delay cost time on the track.

Have you logged pedal position vs throttle plate angle? I see about a 50-70ms delay, max. How much of that do you think is from the throttle body servos?

Good luck removing that via map change.

So, kill LSD and DASHPOT and change requested pressure ratio at throttle at lower pressures so it keeps throttle somewhat shut and WGDC at max.

Other shit needs code changes.
