Here is the setup. 30lb injectors, Vortech FMU with 8:1 disk, SAFC. same car i posted about before. i didnt setup his SAFC for him, but while driving it, i noticed it was bogging out everytime around the 75% throttle range. i checked his Hi/Low settings, sure enough his high was set at 76 and his low at 72! i changed them to 50 Hi and 35 Low, and now the car is cutting out at 50% throttle for a little while, then it seems to open back up and run normal after staying on the gas for a little bit, just as before. the A/F gauge goes lean during these "bogs", but the car is getting enough fuel. after it gets through this spot in the throttle percentage, it runs fine, reading .95 on the digital gauge. its like it bogs down at the high throttle percentage mark, then after it gets past it a bit, it boosts fine. im perplexed. i guess we will just have to fiddle with Hi/Low settings unless someone knows what else to try. mine never did this, has it happened to anyone else? i double checked his wiring and it looked fine. im hoping someone else has had this problem and knows what to check.
