Hey guys, I have a Turbo 1990 Supra. When I press the pedal down while driving it cuts out at around 4000RPM's. It started doing this after I installed my SAFC-2. When this started, the upgrades i had on the car was Lexus AFM, BIC DDP, MHG, ARP bolts and an intercooler kit. everything else is stock. I had a feeling that it would be the fuel injectors because a bunch of threads said its what could cause it to cut out like that, then I also seen on a thread or two that even with the Lexus afm you could still tune the stock injectors with a safc... at least to run like stock. Sooo I took it to get it dyno tuned by this shop near my place, i figured since 90% of the threads i searched for said, TAKE IT TO GET TUNED.. so I did. BUT when he dyno'd it he said i wasn't getting enough fuel, so i was like okay, I'll just get the injectors then since its most common with the SAFC-2+Lexus AFM+550cc upgrade. I finally got the injectors, left the safc the way the mechanic at that shop had the safc set, and still no dice. still cutting out at 4k, but sometimes when i press the pedal slowly it wont cut out at 4k, just does it when i am accelerating fast. Do I need to take it to get tuned again so he can mess with the safc with the 550cc injectors now?
A few threads recommend getting a FPR and a New fuel pump which will be next payday after i get a wideband. Thanks again guys, appreciate the help.
