The car is a 91 Supra running a single turbo Aristo swap. It's been running now for about 9 months with no major tuning issues. I'm rocking the factory ecu.

The problem im running into is that I can't floor it, everytime I give ot 100% throttle it falls on its face. I've done some research and have found some info regarding a neutral safety switch and the ecu thinking the car is in gear or not in gear. If anybody has any information on this could you please chime in. Not too good at wiring but if given specific instructions I can follow.


Any help is appreciated.

Thanks,
Josh

Its the oddest thing though, it idles perfect. It runs great,no misfires or anything as long as I drive it normal but as soon as I give it full throttle it feels like I'm stepping on the brakes literally. Something is definately wrong. I've been putting up with it for 9 months now buyt its getting really old. Don't have a clue.

Just so this doesn't stay an open issue, I finally figured out the fuel pump was running on low voltage the whole damn time. Gave it constant 12v and problem fixed, thanks to all who chimed in to lend a hand.
