im up in greeley is my home base. You need to join coloradoLSX.com Thats where i found my tunner. His name is Clint runs a company with a partner called A.I.R.. i believe Altitude Intense Racing. His shop is in brighton. how ever he does his dyno tunes usually at dynopros off of Peco's and I-76 in Denver. I know he has traveled down to the springs to do a dyno tune before. Join up over there bunch of nice guys and i wont feel so lonely as the only one with a LS4.. I had got a small meet together right after i joined there actually. Ya id be really curious as to what numbers you would be putting down. If they were close to mine or not. My name is the same over there. nice having some guys close to home to deal with. SORRY mods hope im not breaking any rules far as sponserships on the site.
