Above 4k rpm it rips hard no stuttering/misfire/hesitation, below 4k rpms it does all of that. Swapped a new o2 sensor(oem) and new spark plugs (bkr6e). looked over for boost leaks as well found none. I Just imported the car 90 180sx so im finding all the mods as i dig in. Where should i start next
Here's what i know it has so far.
Swapped to a red top SR
z32 maf
Trust FMIC
Power enterprise turbo
3" turbo back exhaust
Has a different ecu from "Technical shop ADVANCE original SPL ROM MT2000 real time rom emulator map tracer"
