I may have figured out my detonation and lean AFR problem.....
For those that don't know I ran 3 times at Steele and had to let off at 1100' for detonation one time and lean AFR twice. (tried 3 different tunes).
Well I just found out that the fuel pump that I installed was not a SVT Focus pump, it was a regular Focus pump. So I am running a 381.5 rwhp motor on a 90 rwhp pump. Does anyone hear think that might be my problem?? |

I had a guy who WORKS the parts dept at a Ford dealership try to tell me that all focus pumps were the same.

Re: I may have figured out my detnation and lean AFR problem.....
by the way, could you see your fuel pressure when making those runs?

If that's your problem then you should've seen a drop in fuel pressure.

When you figure out the detonation problem, let me know too!

It would scare me just seeing the a/f run at 12:0.
