Latinwrlord Posted August 6, 2014 Report Share Posted August 6, 2014 (edited) I have an 09 Gt500. I have the Diablo Sport T1000 tuner. Currently have their 93 octane with FRP CAI, with 2.7" pulley tune installed. It has been working fine even though I have a 2.5" pulley installed. I just finished installing the Dynatech long tubes with their 3" high flow cats and 3" x-pipe dumping into 2.5" pipes to Borla S type mufflers. The car is not performing like she should. I can feel she is off. Waiting on a price from Diablo Sports site on a price for a emailed tune. But they have an authorized dealer performing dyno tunes. They want $399 for dyno time and tune. Seemed a little pricey. Buy haven't done this in a while. So, not sure. Advice appreciated. I have heard the cars are predictable and don't need dynoed all the time with all the base line info out there. ???
