Recently ive installed a LSA supercharger on my 2004 LS1 GTO, Car ran flawless SD, before the charger. Now i cant get it to take off under load, runs good under light throttle. MAF frequency seems consistent, TPS Ramps up and reacts Perfect. Thought it was spark blowout. I put BR7FE gapped a .022, not convinced its Spark blowout, but almost acts as if its on a limiter/anti lag. Does it in any gear, any rpm, fuel pressure doesnt drop, pops and sputters and carries on when i get into the throttle. Having it tuned by a very reputable tuner, and hes conviced its an issue with my car. LS3 card style MAF, 3-bar Map, DW300c fuel pump, FIC 1000 injectors. Ill post a log, anytime car is under load with 50%throttle or close to it, sounds rough. Giving up on logs and trying new tunes. Doesnt seem to react to more fuel, less fuel. Does run a P0101, P0102, P0103 code. Any help... Im Ignorant when it comes to HP tuners, but Im trying to learn.
