I just got the tuner for my 2003 suburban 8.1l and installed the 91 tune.
Now my question is the Transmission shifts hard into 2nd and 3rd and in reverse the idle surges.
I was going to install the 87 tune and see how it does.
Is the hard shifting normal or should I return it to stock and try to install the tune again

grab copies of the files from the tunes folder on the i drive and post them here and we'll fix it.

Re: New tune on 8.1 suburban
How do I turn the Transmission to factory but leave the tune alone? Truck runs great but shifts very hard.
Re: New tune on 8.1 suburban
you can't... takes a custom tune to do it, like I replied to your email about...
