I asked for a refund because I made no where near his power claims. He said, He stated, that it is impossibly for an email tune to beat a custom tune. He said I must have bad gas, or a bad this/that. After the run around, he said he could add a few degrees of timing and lean it out a bit.

But in the end, it wouldnt have really been any better than my tuners tune.

 

I was wondering the same thing, so i called Brenspeed and was quoted $2600 for everything. That is purchase of Comp Cams NSR Stage 2, Pypes LT headers with catted H pipe, 2 new cam phaser bolts, and installation of both headers and cams, as well as a custom tune. From what i can tell and have researched the Pypes headers are almost identical in design to the Kooks for A LOT less....
The only thing that is stopping me is for that much money i could make a hell of a dent into the purchase and installation of a supercharger.....
