Thanks for the info on the muffler Rev. I'm sure it won't make any difference in performance at all...I just want a little more "gurble" along the way to work to drown out the fart pipes.....
The 05 GT is going to make benchmarking at the track a blast no matter what! LOL.... I absolutly agree with the Tire Pressure @ Dyno... Climate control issues can also vary the outcome.... Track and driver response in a "real world" environment over an extended period of time will give us a better idea.... Either way, I have the opinion that this may be the best modulated 4.6/chassis set-up to date..... at least for a daily driver with Nuts... LOL...again, getting the rear end optimize at launch may be tricky and a little more expense than the Fox and SN95.
Have a nice weekend and take care of yourself.
