Hey! I'm new to the site but just wanted to give you guys some information that might suprise you. I have a 2005 GP GXP with CAI, 3" Mandrel bent exhaust no res or mufflers and Overkill ECM/TCM. My buddy has a 2007 GP GXP with CAI, 2.5 exhaust no res or mufflers and a Cortex tuner. We wanted to have a little run to see if there were any differences seeing as both are cars will modded basically the same but with different tunes.
Results, from a dig I got him by a car by the end of first then steadily walking to the top of second and so on. From a roll I had about 1.5 car on him by the end of it.
Just thought I would let you guys know! I thought the results were interesting
