i'm using uberdata 1.7 in my boosted ride. it was street tuned with an FJO wbo2 and it drives great except for stalling during deceleration after hitting boost. lets say, if my TPS voltage at closed throttle is 0.36V and i adjusted the TPS so it will read approximately 0.5V like what HELMS manual states, will this change the original tuning of my engine completely? if so, would it run leaner or richer? is re-tuning necessary or it's not a big deal?

 

it may affect your street tune. your probably going to have to re-tune a little after you fix the problem.

it's supposed to read 0.5v at idle.......a 0.36V TPS at closed throttle would defiantly cause stalling on decell.
