Stock Allison HP

[zstyleracing]

I have a 03 Duramax with a intake, exhaust, and a ppe standard tune. How much power does a stock Allison handle?

Im going to be like farmkid and post what others have said instead of real world experience and say around 90.

the general rule is 90 hp at the wheels

That is what I've herd. I was hoping I could run more! It's time to upgrade.
