When you talk to them about the tune, tell them what your setup is now...not what you hope to do down the road. You'll avoid some heartburn that way...

so a Nelson tune will void the warranty?

If they find out and are not customer friendly.

I would only make it an issue if the trans was broken or the PCM itself was at fault.

It's usually a non-issue and it takes a lot for me to say that.

I had a 2001 silvy that nelson tuned well over a year ago, and I had your basic bolt on's. Cai, Tb,tb spacer, wires. I had them firm up the shifts and never had a problem, and I drive my truck hard someties. My current set up is Cai, E-fans, 180 t-stat, 80mm tb, granetelli maf, and granetelli wires. I had my Nelson tune set up for all of that plus the trans go hd-2 trans kit and the Corvette servos. All the work is done and boy does she hit gears in a good way now. I can chirp second with my 275/60/17 tires with my 4.8L. Just be easy on your truck and don't drive it like you stole it all the time and it will hold up. Gears and a converter is next on the list for me, and I am sure it will be even better. Good luck on your project...... Mark

i had a Nelson Tune before Pu$$y had you!, lol

Dang thats an old tune might need a time machine 88.8 MPH

NO!

You'd need 1.1 Gigawatts.....:LOL:

so do the guys at nelson have a habit of not calling back?

i'm working on finding all the parts for a 5.3 swap & found out what a pain my harness is going to be to find & thought of getting them to make one. i've called them for 2 days & the best i get is the lady taking my name & number... again.
