I purchased a used kit for my 99 5.3L GMC. I needed a few odds and ends to make it fit my truck as it was for a 03. They're abit steep on their pricing (like $60 for directions!) I also sent my ECU in for their tuning, needless to say I would have been better off doing my own w/ LS1 edit. It prett much sucked everwhere (pinging, lean codes etc) This was for a stock truck, I expected to be somewhat close if they did their kit built around a stock vehicle.
Their customer service was fair. I had to follow up a few times as I never got a call back in timely manner.
If the tune was right, it makes good power from a non-intercooled 7lbs of boost. It's definatly comes on right off throttle which is nice.
