Bit o' background: I have a 1991 Thunderbird 5.0 long block in my GT. The 91-93 T-Bird long block is the same as the 94-95 Mustang 5.0, except the camshaft is the 93-95 Cobra cam. The engine runs well enough using the UP40 tune, but I'm sure I would benefit from a tune for the camshaft. I have a Moates chip so I can change the tune myself.

I don't have a Quarterhorse or a wideband, but I have managed to find binaries for the 91 T-Bird 5.0 computer. Are there any data tables I can conveniently copy over from the 91 T-Bird tune to mine? While I'm sure a custom tune would be more efficient, the stock 91 T-Bird tune would certainly be a step closer.

Any ideas?

Engine Suggestions on an engine rebuild. Stock cam/GT40Ps or aftermarket on both for a fun weekend driver?
