I tuned my brothers 07 GMC Classic LBZ to about 100 extra HP - problem is after you run it it idles like its got a cam - I only added fuel and PW no timing - obviously it has something to do with my tune but what would it be? Any help would be greatly appreciated.
You might want to post the stock & modified files.
It doesn't have to be perfect, it just needs to be done in two weeks...

Here are my files:
Stock - Attachment 14117
!00-120 HP - Attachment 14118
Thanks
Here is a scan from the stock tune, if it helps.

Guy you have added IPW down to idle. Try adding from 30mm3 up. Try small increments. If you add to much to soon the driveability will suck.

Thanks, I will try that - I'm thinking of backing the whole tune down to save the tranny.
Guy, your tune is not strong enough to tear up the trans any time soon.
Thanks.
