Another stage I package installed on this 8sp Auto C7Z. Because of the gearing, we dyno these cars in 5th gear which is not 1.1 so the dyno numbers are a little lower than what it would be if did dyno in 1.1 ratio. Either way, the before and after results speak for themselves. Would love to see drag radials on this car and have it hit the 1/4 strip. Enjoy
