yeah i have fuel management in the way of an S-AFC, its not installed though. but the car at first was running fine with a bad hesitation. the check engine light said that o2 sensors, map sensor, iat sensor, and maf sensors where bad. so i bought new o2 sensors, and that didnt work, so then i replaced the MAP sensor and it was still there, so i bought a used MAF sensor that was unhacked with all the honeycombs and the bottom screw on the MAF still was there untouched, and it still had the hesitation. so i knew the TPS sensor only had 1 bolt in cause it broke off in the TB. so i did a 1g 60mm TB swap and know it runs rich as hell! i followed the guide on Road race enginerring to do the swap with all the vaccum lines. all the sensors on the 1g TB fit fine on my 2g. but know it runs so rich that it idles a little rough with light black smoke, but when i floor it, it wont rev past 2000 rpms and there is really big puffs of black smoke. and the only thing the check enine light trips is the maf sensor/IAT sensor and Map sensor.
