I have not tuned it yet. I put the came in more for price ($99) but will eventually have boost. I didn't think it would be this bad. Specs are 211/230 and .558/.552 lift with 1.7 rockers and a 122.5 lsa. Gonna start looking at an NA cam from LJMS or LG. I have a G6X3 cam in my C5 ZO6 and it is beastly. Makes 507/491 on 93. The 4.8 cam was worn out and you could see rub marks all over it. There was bearing material in the cam faces. I put new bearings and a new camshaft in.
