Hey guys. I just finished my big turbo setup, and new full 3 inch exhaust. Upon driving the car when the secondarys would try to come on, it would sputter while they were trying to stage. Steve told me to add some fuel to the map...but how much should i have to add? All my values 3k and up were 0.0%, i added it to 0.9% across the board and it helped alot. i then added .2 more % and it pretty much got rid of it. Does anyone have there values for an FC with a upgraded(around to4r) my turbo is a t66, stock ports, full 3 inch exhaust, 1600 secondarys on an lt8s. I just want to make sure im not adding way to much to compensate for another problem and just dont know it. Thanks

 

Only way to tell if your adding to much is by using a wideband meter.
But if you have added fuel and the stutter is pretty much gone you wouldnt be hurting the motor by having alittle too much fuel in their.
as long as its not lean.
