Ok I just got my car tuned at Revxtreme and Jeremy told me that I didnt have the ls6 manifold even though I thought I did. He said because it had egr provisions that it wasnt an ls6, I got it from my friend and he said it was a ls6, but I just took his word. Are all ls6 manifolds without EGR or were there some. Also if I have an ls1 intake manifold how much is that holding me back on my dyno numbers. I hit 370 hp with the mods in the sig, with a question mark on the intake manifold.

Unless its from SLP then it's an ls1 intake. SLP is the only one that I know that makes one with EGR provisions

LPE also makes an adaptor/provision for using EGR on an LS6 intake and I wouldn't doubt that there are other ways to possibly make it work.
If you do in fact have the LS1 and not the LS6 then it's holding you back at least 7-10rwhp.

You'll see a nice gain with that cam. I bet you'll pick up atleast 15rwhp if you get the LS6 intake. I had very good gains and I have the TR224.

In the middle between the fuel injectors. Here's the breakdown.

The Z06 LS6 is 12573572.

The old LS1 intake with the EGR setup is 12560688.

97-00 vette LS1 part # is 12556333

Ok this is weird because I have 12573572 on the intake manifold but it has egr provisions, anyone seen this before?

Yes, on an SLP 'EGR modified' LS6 intake, that must be what you have.

If it looks like the stock egr kookup then it's a Lingenfelter adapter on it I had one on my old LS6 intake. If it looks like a threaded peice of tubing in the egr area of the intake then it's the SLP LS6 intake.
