Ported TB gain

Re: Ported TB gain
If you port the TB thats gonna cause problems I believe. Because the throttle positioning sensor is gonna say your 25% open when your flowing 28% air?
I don't see how thats going to work out.
Also Madwolf stated he actually experienced a loss in power and does not recommend them. Some people say they are good, but I've not seen any definitive dyno testing.

Re: Ported TB gain
My own experience:
Hooker cat back exhaust - not much difference
K&N Filtercharger - not much difference
52 mm ported stock TB - woke up the car.
Probable cause - finished opening up the flow of air/fuel. The exhaust and intake allowed more air, but the tb was a bottleneck. When the ported tb was installed, it allowed the other components to work to their potential.
I gained .1 to .2 in the quarter mile.
Just my $0.02 worth.
