Can not re-load canned tunes

[tohi2care]

I can't download my tunes because when I do it says "Unable to locate a valid Target Instruction file." I made a post about the problem and you posted that you would mention it to bill when he gets in. Heres the link to the thread.

Ok got my canned tunes loaded back in and all I can say is..."GLAD TO BE TUNED AGAIN" It's a different truck.

1 question. I always ran the 87 towing tune before getting my custom tunes.

Can I run the 91 performance tune WITHOUT running 91 octane gas? Would it be any improved performance?

No,
The 87 has specific air fuel maps for that octane as does the 91. Eventhough they are generic tunes. I am sure through timing changes it would be possible but with only Bill to change the AF mapping. I wouldn't recommend it.
Wait to see what Jack says.

Fair enuf. I did try it once prior to getting my custom tunes but I also put in the 91octane gas.

I'll just wait to get my 87 perf tune back from Bill.
