ok,if you have alot of differant tunes and cant remember witch one is in the truck how can you find out.the tuner just says sct tune so that doesnt tell me anything.has to be a way to find out but i cant figure it out.HELP!

 

Why dont you return it to stock, and load the tune you want?

 

I think, and don't hold me to this until I test it tomorrow...or when Mike T chimes in, but when you plug in your tuner it will only let you upload a tune that is not currently loaded...for instance:

Say you have the 92 perf tune loaded. The tuner screen will look something like this:

Select:
Stock
83 perf
83 Tow

It will not have a 92 perf tune on the list. I know it doesn't tell you what's in there, or maybe it does, but if you know what tunes you have you can deduce what is in the PCM by what's not on the list.

Of course I could be way off in which case you just wasted 45seconds of your life by reading this..
