My SS has been LS1Edited but I would like to have the shift point changed. The shop that did the tuning has closed down and the new one wants like way to much money... I have a Hypertech. Can I use it to change the shift points and/or firmness without it change any or all of the other stuff Ls1Edit did???

 

Don't. or you will risk losing your custom tune.

Doesn't it say directly in the HPPIII instructions to only use it on a stock PCM? I could have swore there was something in there about that....and for good reason.

 

Damn. Guess I'll have to pay up for another tune. Thanks for the advice.
