Been thinking about joining this site for awhile and now here I am.  I have an 06 Pontiac GTO and I know I have seen alot of you all at the Test-n-Tunes.  Thanks to Anthony for the last couple, the last one being at National Trails a couple of Friday's ago.  Congradulation Anthony on your Marriage.  Here are my modification to my Gto as follows: 
Mod's: MOTOR: 1 3/4" Kooks Long Tube Headers with High Flow Catts, SLP Underdrive Pulley, Cam, Vararam CAI, & GMM Ripter Shifter. 
Cam Spec's: 230 Intake Duration, 232 Exhaust Duration, .595"/.585", 113 LSA with 109 Intake Centerline @ 2400-6400 RPM. 
SUSPENSION: Serious Street Pedders Package. Harrop Differential Cover  
Best Time: 12.60, Best Reaction Time: .019 
Stock numbers: 339.2 RWHP. 347.4 RWTQ. Current: 406.2 RWHP 384.2 RWTQ (I need to get onto a Dyno to see my new numbers cause I think I atleast have around 420 now).   
I look forward to some more Test-n-Tunes and hopefully with you all.  Here are some pictures of my GTO.  I also have a 1979 Pontiac Firebird Formula needs some work.  I know one of these winters I will dig into it.  So enjoy and hope to join this site.
