I had it in my 5.7L basically stock engine and it ran fine even with just a crack of the throttle. Allen had it tuned to run pretty good in my truck. We never finished the tune due to my transmission taking a crap on us and a rain storm blew through closing the track down for the night. You're more than welcome to call Comp with the cam specs and ask their opinion of it in your application. It's a badass cam and it really sounds sweet. My truck was used as a daily driver and I loved the instant off throttle power it put out. I can only imagine how much better it would work with a turbo in front of it. The tech guy at Comp asked me why I was running it without a blower though. He said it was inefficient without some kind of FI.
