dang 50-60 more h/p from a chassis dyno tune ? who did your tuneing ? I was going to get a chassis dyno done here local on my lq4 6.0 but they wanted $500 which I thought was high but if I can get more h/p numbers like the 50-60 I would go get that done . I didn't want to go thru head and cam swaps.
