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

I'm trying to get dynoed by the end of this year and since there's no local track I have no where to go atm . my app says I'm 13.2 but that's far from being a dead nuts figure
 
I have the diablo trinity and its all ive had so I cant compare, but stock to the diablo is night and day. I also put my shift limiter at 6150 so I don't hit in while in tapshift.
