so i got the cam in last weekend. about a 2.5 hour job. i'm working on the tune now. its not a huge cam but it is all out of wack in the tune. it died a few times on the ls6 cam tune. light light throttle it was rich. every where else it was lean lean. half throttle feel strong and the turbo seems to come on faster than before with the ls6 cam. i only got one wot run and it was very short but it was harsh. its been raining i hit it at 40-50 in the rain and it was all over the place. which for my Tahoe is saying something cause with my weight over the rear and good tires it doesn't break loose at that speed. this weekend goes back in the AWD and the trutrac!!! woot!
