Install the Diablo tune and modify it for the 4.10 gears and go from there.

Thanks

I was told that the Diablo tune from the factory would lean it out to much. Is that true ??

[mikel]

No.

Does anyone else have any idea how I should set the parameters for the air or fuel? Thanks

you shouldnot mess with air/fuel unless you have a wideband air/fuel guage. you should really have it dynoed if you wanna mess with that

with my mustang its a 00gt i only set the odbII to turn off the rear o2 sensors, advance timing all the way in the 2-4 k and 4-6k range and set the gears to 4.10. and that was all modified with the performance tune.

Whats the difference between the Diablo tune , factory hp tune , and the tune original in the car? Thanks
