This intrigues me. Do you know why? I would have thought the egr-effect of more overlap would lessen the chance of detonation. In that case, would it help to run a turbo with a larger hotside and keep backpressure down?

my 215/218 use to chop pretty good. but after i finished up the tune it idles like stock but more girgle to it. if you leave the idle a bit lean it will lope a bit more. so you don't have to have such a huge cam. but at the same time, if you tune it properly most of the lope will go away unless its a bigger cam.

When I first turboed the truck I had a 218/224 .600/.605 111lsa cam and it was a very choppy cam, felt good and drove with good maanners. But a lifter took out that cam. So now I have a (stock48) isky triple 12, and it's bad ***. Has a mild lope but it makes more power and drives even better.
This is the 218/224

Yeah, thats what I've been thinking also. Leave my 216/220 in 110 cam in my 4.8 and try it with a turbo. N/A it takes off right at about 3000 rpm, so I got a PI 3600 stall when I got my 4l80. 4.8's love to rev, so I can't really see restricting that with a turbo that chokes the exhaust at high rpm. Plus, I really like this cam currently. Its still pulling at 7000, and falls off shortly after that. Ideally, I want to build a system that amplifies what I already have.
