03 Silverado 6 Ltr

[03FullPull]

Does anybody happen to have a performance tune for a 03 3/4 ton Silverado
Just looking to make it a little quicker and firmness of the shift to be better. This is a stock truck and I was wondering if there was a way to make it so the tow haul button can control performance and stock tunes.

Thanks 03FullPull

I would like to help but I'd prefer not to publicly post my tune. I don't know how to attach files to a PM. If you want to PM me your e-mail address I can send it to you.

ooooo magical tunes. J-K I no longer post mine either.

Tow haul can only change transmission settings.

Only a handful of things you can do to a stock vehicle, especially without a wideband. lean it out a bit. Take off the PE delay if it there, and find some decent spark tables off here.

This is for a truck I have been working on. I have an 03 5.3L with cam, zo6 valve springs and push rods, cold air, Flowmaster Exhaust and EFI Tuned. I am sitting at a little over 300 rwhp. got anything else that could help me other than a 6.0L.
I am a big truck puller and I like beating 6.0L with a 5.3L. Thanks for all your help and info.
