Hi guys
good day
I faced an issue with a GMC Sierra 2020 that has a Whipple 3.0L supercharger and LT4 injectors the issue occurs after installing the LT4 injectors.
so after we did install the LT4 injectors on the truck I did put all the injectors data and calibrate the MAF to get the fuel trims in place but the weird thing that happens is that the throttle response has been too aggressive and the truck in not drivable but when I get the old MAF calibration on the truck it runs drives fine but the fuel trims is -29% which is bad.
I think it has some think to do with the Virtual torque since these trucks are torque based
I wanted to share this and get the advice form you guys
thanks a lot
