so i got a tune from a reputable shop in my area. I loaded it and the car starts then cuts off. will do this all night long. if i disconnect the coolant temp sensor , and intake air temp sensor it will fire run for 3 seconds then cut off. after about 20 mins of this it will fire and stay running but will not rev over 3000 rpm. . . . .
the computer is a 02 silverado 5.3 , no mass air , i did re run the intake air temp wires. no rear 02 sensors , has a gm three bar map , 5.3 with a 76mm turbo., 96lb injectors( updated from last time. ) e-85 set at 50 psi fuel pressure. mild cam. prop form intake 102mm intake. i dont have a data log as i dont want to keep doing this to the motor. so any thing i can look for before doing a data log tonight. . . thanks for the help
