Default Tuning problems

Well I finally got a chance to try out the new L-36 intake. The exhaust definitly picked up a deeper tone over the LS-4 intake, power wise it's hard to tell, it's picked up quite the bog between gear shifts at WOT coming from a start. Runs fine through first, push the clutch in and put into 2nd then let out the clutch and punch it and it lays down for about a 1/2 second and then goes great, same for third and fourth. The sad thing is that it didn't have this problem with the LS-4 intake, actually I finally got this tuned out of the LS-4 intake with the secondary air valve spring so this setting was the same going on the LS-6 intake and now it picked up this bog. I tried tightening the secondary air valve spring but this dind't help any and only lost power. So I started over and went from the point that the spring will just barely close the secondary air valve and then went a 1/2 turn tighter from there, power is better but the bog is still there. Anybody have any ideas that could possibly help me out :confused:

Thanks
:cheers:

Cann't help on tuning. How did the manifold fit, can you use the stock air cleaner? Which L-36 intake did you use 793-801-849?

Thanks

Intake bolted right up, I'm using the stock air cleaner and assembly on it, no clearance issues that I can tell. You'll have to modify a 68 choke a little bit to get it to work with the 73 linkage and bolt up to the intake manifold. I used the 849 intake.
