ok guys so i got my ttz dynoed the other day and i am supposed to be making around 350wrhp but I only made 285.. at 5500 there is a HUGE drop in horsepower, i go from 270hp at 5500rpm to 196 at 5600rpm and by the time it hits 6000rpm i only only producing 175hp.. My air/fuel ratios are off the charts as well. The car has boost jets running @ 15psi, full exhausts, 615 cc nissan injectors, pop charger, ashsepc ecu upgrade. Now I am running very rich in the mid range rpm and very lean at the higher rpm, I would told that my ecu might not be re-mapped right? If anyone would have any suggestions on what to check I would really appreciate it!!
