problem= rb25det s1 is dropping power at 9-10lbs at full throttle.
Reason = from what ive understood by research is maf is maxing out in voltage and ecu is cutting fuel and spark after retarding timing.
driving the car and giving full throttle there is an obvious 20-30 hp loss at higher rpms. if i stay in full throttle the car will just like hit a dead spot where the afrs go off the meter. if i roll into it its all power is there seems like the maf freaks the computer out when I full throttle quickly.
I want to find a way around not turning down boost and not buying something to tune with. From what i understand the n60 or the n62 maf could work but unsure if i will absolutely need a tune.
on the dyno i made 280 but when ecu took over with the timing shit i made 250-255. car does have adjustable fpr.
Any helpful input is much appreciated!!
