So to answer your question: the leak did not effect the performance of the GTM SC kit.

That being said, I'm still waiting to see the HP/TRQ ratings on the dyno on a stage 2 or 3 GTM SC kit to see what it can do, regardless of the boost pressure. It's the efficiency of the power a kit makes that separates it from the rest ...... not the boost number. IF the GTM SC kit makes 500 HP @ 2 psi boost ...... I'd be impressed!

A boost leak is a leak regardless of how minimal it may be. The higher you try to turn the boost up the greater the leak will become. In addition, if Sam is such a perfectionist, than why was the car not dynoed with the headers after the boost leak was rectified! That is the first thing I would have done. But at that point he had already convinced Shumby to put the stock manifolds and stock cats back on the car.

I would never market a product with the selling point of having to keep stock manifolds and cats to make power. This is HORRIBLE advice and it goes against everything that has been proven with superchargers for decades.

The bottom line is that specific kit is inefficient and apparently isn't creating enough volume to make power through the headers. I have no doubt we will have no issues making power through the Stillen kit.

Now you have our headers as well and are going with a larger head unit. Your results may be positive. I am in for results and hopefully from an independent dyno, not GTM's!

Thanks, Tony
