Iv been having troubles with detonation with my 99 gt. Its a s/c fully built motor that iv built twice already due to a main bearing gone and a hole in a piston. Now I just got it done again a little over a month ago and bought a 95mm maf because I thought the stock one was pegging out and thats what caused it. Now it seems like its doing it all over again. It gets to about 6000 rpms and falls on its face it seems but the first couple weeks it ran smooth and had alot more power. I have 44lb injectors with 255 pump and stock fuel rails and regulator and a rough tune from Snipers stand alone. Can someone help me before I have to say the third times a charm.
