Of course Im talking about stock pistons....why would I be talking about dumping aftermarket ones?

Yes Im talking about stock cast 6.1 slugs - general opinion being any sort of boost over 6psi sees you losing the top ring land after a while...

If you disagree...Im sure others will verify that this is the commonly held opinion....

However not sure if te 5.7s suffer from the same issue?



I wouldn't argue with him. He understands the tuning more than 99% of us.

Boost isn't always boost. Certain kinds are more forgiving than others. There are exceptions to every rule.

People are putting nitrous and 10+ lbs of boost through stock 6.1's. A good tuner is what links all of those people together.
