Ran my buddies (02bigstrokin) 03 duramax on the rollers today after installing set of hamilton's new duramax valve springs. Did a before and after run and picked up 100hp with the springs installed. Guess the stock springs weren't closing all the way like they should have been.

Thanks for the sponsorship and all the help Zach:rockwoot:
