I had my 04 gto tuned. the guy used c.a.t.s to do the tune.

I have a diablosport slp tuner.My ? is can i use it to change my shift point's as long as i just modify the stock tune and not install the slp tune.

I basicly want to turn the shift point's up and have control of my fan's off/on with out takeing it back in for a retune.

I think the diablo pull's what ever is in the pcm and calls it stock. but i am not sure

any help would be great

thank's

If he didn't lock the tune you should be able to modify it.

 

What he said...Yes!

 

thanks guy's. I am new to the tuning part. this site is the best.

thanks again

mike
