This is driving me nuts. I must be missing somthing. Its a 05 GTO auto with MAGI tvs1900 that im trying to run it SD but any time I go to start it soaks the plugs it cranks in 25/ 35 msec. Iv tryed every witch way so the one im posting is just a different try. Stockish tune with stock map sensor (ls9 injectors,no maf and 2bar is not applied at the moment). please someone have a answer.
