just finished ls6 intake manifold install
i thought the gains were noticeable. i changed my oil pressure sensor while i was at it. i also cleaned all the gunk out of the heads (IT WAS HORRIBLE). my car has 100k miles. i also cleaned the throttle body which was a bit dirty also. i cut away the ribs so i could keep the stock coolant pipes and it worked fantastic. i really didnt think i would notice much of a difference. i think a lot of it may have had to do with cleaning all the gunk out of the heads.

Did mine a couple weeks ago. The gains are solid. Install wasn't bad.
Let me know if you see anything funny with your DIC and various readings.

Manual. My car is a 99. 2001 and up already have the LS6 intake. I mention this only cause I've seen some people run out and buy a new intake hoping for some improvement, and they already had it. My next upgrade is going to be a ported throttle body and I'll see if that's a gain you can feel for under $100. bucks.

Went the same route you're going;
I installed a LS6 IM on my FRC while I was replacing my OPS...I then had a set of 1 3/4" LT's installed with my Z06 Ti's with my factory X-pipe...
I then had it dyno tuned by Dr Phil...If you haven't decided on a tuner, I highly recommend Phil (he's in Macomb County)..

throttlebody will give you a couple of hp maybe even 6 or 8
on the outside but the best part is immediate throttle response.
You will think you have picked up 25 hp. Have fun.
