I gtech every mod I do, I've sent several items back. The airfoil is one I should have sent back as well, but kept for some reason. The granatelli MAF also got sent back.
Best mods for me were LT headers and 52mm TB. All the other things I've done may have helped slightly, but those two mods were best by far. The granatelli actually cost me power.
thanx....real data is priceless.
i've got the airfoil from my tpi hanging on the wall...just ''looks'' like it should work....guess its of more use on the wall (icandy?) than it would be in the intake, and i don't need to worry about the screw falling out and in.

Wrong magazine.
Wasn't CandD that found out they don't do anything but lighten your wallet.
We have a 1985 school bus converted to a motorhome for our church Ministry. The bus has an International 6.9 diesel Engine. Before we had the 'Fuel Genie' installed, we were getting 9.8 mpg at best. Since we had the 'Fuel Genie' installed, we are getting 15.26 mpg.That is a 50% saving! We have triple and quadruple checked the figures! If you can't believe this, niether can we, but it is true!
The tornado came in my car when i purchased it and I did not know it at first and when i took the hose off to replace it(was a hole in it) i forgot to put it back in and drove around got home and freaked out because i thought it was something important so i looked it up on the internet saw the bs and gave it to a buddy who now runs it in his neon. He made it fit to where its bent in there.
