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.



Alex - thx for the civil reply.

Fwiw Im not arguing - Im trying to get to the bottom of why 'most people' say dont do it....

And its in my nature to test the water to make sure its deep enough for swimming

Hopefully Badx will post and clarify why this mis-information exists...
