[Phantom]

At least it has a slight chance of being better than the tornado. Why do I say this since it is placed after the Throttle Body (TB) so it will not have the MAF screen and throttle plate to clean the air flow. Also if installed before the MAF it might not see all the air and mess up the fueling.

To think instead of installing a larger ported TB to help remove a restriction and increase VE (volumetric efficiency) I should have just plugged the intake to create a restriction.

If anyone would want this tested out you can order me one and I can post raw MAF, fuel trims, and almost any other data you would want. All you have to do is pay shipping since the posted price for a 2003 Pontiac Grand Prix is $0.
