Update on Air Fuel ratio and Detonation problems...

Quote:
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 got my SVT Focus pump installed at SVP today and sure enough the pump I had in my car wasn't a SVT Focus pump (green top-Ford color codes everything). Now when I go to WOT and get in the boost the AFR is about 11.1-11.2, at the track it had been fluctuating between 12 and 13, so I guess I can take out that 6% extra fuel I programmed in with the Xcal 2.

Glad you got the right pump in Whit.

No, I checked the plastic line and it didn't have any cuts or splits, but I did use the SVT Focus bucket, it was the same as the one in my tank-only newer and not discolored.
