I have one of adams old kits too and we were not to big on the intake so I had them fab me up a new one. Not sure how big of a deal this would make but it had pretty large welds on the inside and the one that I got had hard angles not smooth curves. Not sure how much a big factor this plays into things, I should have mine tuned soon to see what my set up made.
We also changed the direction of his intake to the stock location. This was done so I don't have to change the location of the computer and stuff. I am sure there may be a temp difference, but I highly doubt its going to make a huge difference in performance and if it does, I do have a function cowl hood.
We are tuning on e85, pump, c16, and pump/mix. The pump tune is just a ooo shit i am out of gas type of thing.
