Save your money and just drive stock other than headers, ported TB and such. But I kind of feel those guys didn't know WTF they were doing.🤪

That was an additional 10 hp at the peak (6800 rpm) bigger gains down lower.

"The real story here came after the peak though. While we may have only gained 10 horsepower and 10 lb-ft of torque at peak, out at 6,800 rpm, where we will be shifting the car, the LT1 was up roughly 35 horsepower at the rear wheels, a considerable gain. Since the car will spend more of its time in this area, it’s hard to discount the improvement. On top of that, with the looser torque converter factored in, it’s hard to draw direct parallels to the power improvement, though we were satisfied with what we saw."
