Was thinking if it was the intake manifold, I got this Lingenfelter just sitting around collecting dust from the previous owner who never got around to installing it. Only bad thing is that the retard couldn't find any of the hardware or the gaskets and access cover for the bottom of it. So would have to get the gaskets and either modify the coolant tubes, or get some ls6 ones.
Been trying to find some flow charts for a comparison between the Weiand/Lingenfelter 300-111 and the stock LS1 intake and haven't had much luck. Guessing the numbers aren't that far out enough for them to really show off what the intake will do over the stock one? I have heard numbers as high as 25 extra ponies. Have also done a lot of reading based on the heatsoak over time vs the stock plastic one blah blah blah. Not sure that I put that much stock into the heatsoak theories because the car won't be sitting and idling in traffic much at all and I probably won't be doing any 1/4 runs here anytime soon.
