    Hey, from what I got out of the article, it is more of a reading that the tps gives to the computer as opposed to moving more air with this mod. With the mod, the tps gives a reading closer to 100% throttle opening to the pcm and then it gives you more fuel. That makes sense to me.

    hey, I know it has to add up. I have already done the egr mod, air box ,throttle body coolant bypass. I can't believe they stuck the egr down in the middle of the intake like that. That thing had to be really screwing with the air flow.

    I don't know about the differences between the Camero and the Z28, but I always suspected it was just an air flow thing as far as hp difference between the ws6 and the regular T/A. With just the air box mod alone, I can feel seat of the pants difference in the way the car pulls past 60mph or so.

    Cold air intake is on the way

    Cold air makes a big difference. My IATs stay between 90-95 since I sealed my hood. They averaged 120-130 before.

    Cold air makes a big difference. My IATs have stayed between 90-95 since I sealed my hood. They averaged 120-130 before. This chart shows that FRA is better than unsealed WS6, and that sealed WS6 hood is better than FRA. Someone posted it here a while back. I found it very interesting.
