hey...i see ur a local...was wondering if you could help me out ....got any info on a tuner?

Thanks I have a 2008 GXP has anyone had a pcm/tcm reflash done yet ?
or used pre-flashed ecu's bought online ?
I was looking at Vector Motorsports ecu's I called them to find out if they have DoD delete and more specific info about the tunes but all I got was a receptionist she could not answer my questions
There doesnt seem to be any hand-held programmers for the 2007-2008 5.3 L cars

Just wanted to hit you up to say wuzzup to a fellow Chi-town GTP owner!!!

Peace!
