i went over all the bolts and snuged them up and also did the tb bolts.
ill check the vac lines behind the intake tomorrow.
but wouldent a leak cause the car to run bad at idle?

.. I have a Weiand/Lingenfelter on my turbo car, people said their crap, don't add power, etc I couldn't notice a difference in power but I did have to add fuel to bring my AFR's down. So if I'm adding fuel it means it's flowing more air for the same amount of boost.

If you have a MAF then that it isn't that cut and dry.
sounds like a problem with the install, if you still have the MAF than I don't know how it can run rich. Also you said you took it to the track and it doesn't feel faster? What are your before and after times? Dyno-Proven GM LS1 thru LS7 Performance Parts book the picked up 27hp and 22ft lbs of torque over a LS1 manifold with heads, cam, exhaust.
You need to understand that the MAF uses calculated estimation for airmass reporting; it doesn't measure it all. ANYTHING that changes how or where air moves through the MAF will change the tune. Heck, you can spin a MAF 90 deg in it's original place in the pipe and it's cal will be screwed up...
FWIW, an LS6 will make about the same thing in the setup you cited above over the LS1 intake. I have watched no less than a half-dozen cars gain next to nothing with this BBK intake over their LS6 intakes. To be very specific, they usually lose a few tq digits down low and make 2-4 more up top. To add insult to injury it's very costly and often has seal issues (and hardware backing out)... The MOST I have seen one gain over an LS6 intake was 5rwhp, and that was against the LS6 baseline taken during the summer months. I have had massive fights in the past with leaky BBK TBs too. I just tell my customers to avoid them unless they have already purchased and installed them.
I'm not anti-aluminum, I'm anti-this-BBK-intake.

Are you running open loop or closed loop? If your closed loop, do you have any codes? If not your fueling should be fairly close. If your open loop, you need to find out where your AFR is. If it's way out of wack you likely have a leak.
