I was wondering if my fuel pump needs to be upgraded. I start detonating in 3rd at the track and on the highway when I'm on it. I did the volume test on it right before I did my mods and it was good but barely... Timing is at 12* and I have an adjustable FPR and no matter how pressure I put on it, it still does it(93 octane by the way)... Or could this be my computer. Any help to solve my problem would be greatly appreciated
