Sup guys thanks for looking and for the help in advance so story. Driving down the road car just starts cutting hard goes down to 3 grand and won't go any further then that idk if its limp mode? Boost leak? Or does this car just hate me? Its a rb25det if limp mode does anyone know the correct way to refLash the ECU?

Good bet it's your maf. Check the wiring and all grounds. It just bounces at 3k right? Almost like a limiter?

Yea that's exactly what its doing like a rev limiter that's kinda why I though limp mode but maf was on my mode I checked it out it's tight

It's tight? As in the wiring and all your grounds? The sensor itself could also be bad. That's what your symptoms sound like to me anyway. Get a multiple-meter.

^^ what he said MAF may have gone bad, but then again harness might have funky wiring. You need to check resistance with a multi-meter.

... hehe. "multiple-meter", first time I hear that. :p
