i have few clients on oem engine,Fsu,500+whp/450+/400+and those cars/engines are strong😜 we have to catch that each car/drivers is different and really know read/understand the datalog to make the right adjustment
looked the log sir,it seem you have boost leak,boost command is like 25psi and the car can keep up to get 22psi and the wastegate is maxed out so look for everything😉
a way better read on the race and the ecu is happy to not be maxed out on the maf sensor,even at 380-420whp the race housing is a must in this car,ask your tuner
