    Question OT: Duramax boost question...

    Karl just hooked up his boost gauge on his Duramax and with the chip on stage 4 he's getting 21psi of Boost!!! Does that sound about right? Seems high to me.... we havent put it back to stock to see what it does normally but we were just wondering if anyone else has any reading?

    Money can't buy happiness, but it can buy horsepower. And I've never seen a sad person hauling a$$!

    I believe the dodges are seeing low 20's on a stock motor. 30's on hopped up ones. I didn't believe it the first time I saw the numbers either.
