OK...a quick run down of what has been going on....two years ago I discovered I had a defective cam. Replaced the cam with the exact same grind and now I am down on power. I've used the same exact program as before.
Fortunately I recently discovered a data log at WOT the day before the Mustang layed 617 rwhp to the ground...So today I data logged a WOT run to compare the two. The baffling thing is the motor is ingesting the same amount of air and is running pretty close to the same air/fuel ratio.... The timing is the same as is the boost levels....it just takes several more seconds to run through third gear.....Any ideas????? I would be happy to send both logs to anyone interested at looking....
My combo is a 408 with an S Trim which makes about 8-10 lbs of boost depending on the air...
I don't think its the cam install since it is reading the same VE and psi...
I don't think its a fuel problem as the A/F ratio is 11 to 1....
And if it was an ignition, why would the A/F ratio be the same?
Maybe timing??????
The motor is in good health with 2-3 % leakdown in each cylinder...and I had FAST check out both the actual ECM, MAP and o2 sensor....
