Thanks to PatrickG....
I bothered him,slowhawk,predator for what seems months
Patrick was a complete gentleman and answered ALL of my questions
Even some over and over again

He spec'd me a cam and I was all set to put it in but Comp offered me a great deal on any off the shelf grind in there catalog..It was basically free so I couldnt pass it up..
That being said,Patrick told me for what I wanted to do that the XER273HR14 was the cam..I then saw at least 4 of 5 dyno's using this cam in the last 4 weeks and after getting even more recomendations from Mike Norris,Spinmonster,RyanL I decided Patrick had a winner on his hands and installed in my 06 GTO..
Well it sure was what I wanted,Patrick hit the nail on the head as usual.
Car started right up,held the idle at 795 (I set idle prior to install w/EFI LIVE)
No Surging,no bucking at all..
Just a nice lope and a nice crisp revver,actually loped more than I would imagined...
It drives like stock with no tuning,I cant imagine it needing much more that a tweek to the idle fueling and wot fueling..I have already removed all the codes before I installed it that would cause a SES and so far not one code in 50 miles..
I am dialing the Ltrims now and then we will dyno tune it Thurs..
I cant tell u how happy I am for not putting in something bigger than this cam as its exactly what I wanted in a street/strip setup and my VIG 3200.
I will be adding a Fast and or Weiand to the car along with 3.73's
Thanks again for the cam help Patrick,U are a good guy

All in all I was very happy with that cam choice for a street car and it exceeded my initial goals of wanting an 11.80 street car. times in sig. Good Luck and enjoy your HP.Nice thing about this cam is I picked it up NEW at Summit through my wholesale deal for less than 350.00 to my door.
