Hypereutuetic pistons and nitrous??

Marko Glush at KB is a good dude. Worked with him many years ago.

The ring gaps on the hypers is different because the top ring is closer to the combustion chamber = more heat = wider gaps. Gap them for your end intended use.

Go at least one range colder on plugs and gap them tighter when running juice. Learn to read your plugs if you wish to run nitrous.

A fat N2O tune up is just as bad or worse than a lean tune up IMO.
