ive had probs with the tune on the car getting this right fuel bank and left fule bank code crap. the mechanics been real good about taking car of the prob , but the dam things been in the shop , then out on the street since the fucking tune. it had bad o2 sensors in it when tuning it . took the car into the shop to have the stock cats put on tell they gudded the cats out of the x pipe, he put the thing back on the dyno tuned it and it was fine, took it to the tranny shop , had the shift kit put in then the dam thing threw a check engine lite. took it back to the shop he put two new o2s in and it was running real rich . he said run it for a bit it should be , tell we can put it back on the dyno ,ok got it back to my place of business it was running like shit. had it towed back to the shop where it sits now. what im wondering is why the hell is this thing keep giving me check engine lite all the time. now mind you im not charged for all the times its been back at the shop ,but dam. this is getting old!!! its got the 42 lbs injectors kenny bell blower , 90 mm maf, kb boosta pump , 255 in the tank, forged bottom end and mild ported stock heads. please give me some advise on this thing. im getting ready to take my gun to her soon , lol. thanks gil
