Off the shelf 24# injector tunes for non-cammed s5x engines have proven to run rich up top, killing top end power. I HATED my TMS chip for the 3.5" MAF and 24# injectors. Tried a TRM chip for the same mods and liked it better than the conforti unit.
After all was said and done, I had Osh at RMS dyno tune my car and I made 8whp and 6wtq (232whp/228wtq) more then my TMS chip (224whp/222wtq) WITH 24# injectors. The AFRs were much cleaner with the custom tune, the car made more torque earlier, and pulled much harder in the top end.
This was all for my OBD1 s52 with 24# injectors, 3.5" MAF, eBay headers, single 2.5" exhaust, 13# Fidanza flywheel, and 3.46 gears + ZF320 trans.
