There is a lot more power available. Magnuson's "kit" tune is very safe and conservative. But for approx $10,000.00 installed you get ZO6 power and tq and the kit looks OEM.
The Vettes are so light compared to the Camaros and they seem to hook much better, so the Vettes are really quick and fast.
The new LT1 engine makes more power than GM has it rated at and it's a a bunch more than the 5th Gen.
