ok ill keep it short and sweet i have a vortech with a 2.87 pulley, 600cc injectors, and hfc, with full hks exhaust. had it tuned by rt tuning everything he said came in real well. the car was running very well up until last week when me and a friend of mine were goin over my car and many people have said that it sounds lk i have boost leaks. so we took apart the blow off valve cleaned it out. Then we noticed a huge whole in my inner cooler tube that was cause by a screw that was rubbing over time. i took it off and had a friend weld the pipe closed. put it all back together and the car ran so much strongerfor lk 2 days. Then all of a sudden the car fell on its face. air/fuel gauge is now readeding 10 at 10 psi when the lowest it ever read was lk 13-14 depeneding. Now tuner had my car lk a month ago and was retuning cause i had a issue with hot start and he came back and said that everything was perfect and he still had the hot start problem....... he said it was leaning twards a ECU issue.... Can any one please give me some advice or point me in the right direction to. Please any help!!!!!!!!!
