Done one on an 02 van PCM for the one in my 99 Tahoe. Has the 425 HP Marine cam, shorty headers, full exhaust and marine injectors.Originally Posted by King26matthew
I started looking for the same a week ago. If you use a google search of the forum there is information here on the 8.1L tunes. Some have good information that spells out the changes most do. There are also a few tunes in progress stashed here, but after downloading, I am better off just starting from scratch. Other forums like efilive have 8.1 information on changes that are not hard to follow no matter what software you are using.

I tune 8.1 Vortecs all the time. What are you looking for?
I have done a few myself.
Biggest gains are torque management, PE delay, WOT fueling on a stock engine.
Once you cam them they need a bit more work. They want alot more timing with a cam.
