maf and tb ?

the maf is good for 400hp or so. i wouldnt touch it.
I went with an aftermarket MAF and a 52 mm TB. The MAF is gone, the TB (ported stock) was one of the biggest performance improvements to my then stock car. Now that I have the turbo, I am extremely glad that I did it.

Ignore anyone who tells you to buy MAF ends or to port the MAF. Airfoils are a waste too.
Ported plenum is a waste on as cast heads, once heads are ported it is fine.
You are chasing all the wrong things here.
Hypertech "programmer" is garbage, overpriced garbage at that.
Looking at your mod list in your sig I would say headers is the next thing to do, so stop looking to waste money on piddly little junk that wont do anything and save a few bucks for headers.
A 52mm TB might be worth a SLIGHT amount on a stock engine BUT IMO those who claim it was great are confusing throttle response with power. The bigger opening means more air/power for the same slight throttle openings, at WOT though a stock engine is not signifigantly restricted by a stock TB especially not with stock exhaust manifolds choking it.

For the record, the stock throttle body is good for 500+ FWHP. An airfoil is worth nothing. Removing restrictions ahead of the throttle body will show some slight gains.

Interesting. My car had a CAI and a catback. It would lay 10 feet of rubber from a dig. I put on a ported stock TB. It immediately would lay 20 feet of rubber. No other changes at that time, including tires and tire pressure.

The opening aint the plenum, he asked about a ported plenum so
yourself.koolaid_kid, so do you think you doubled power or what? Road surface and temp can have a huge impact on traction.
I find the

You people need to learn how to think not just read advertizements and catalogues. Reason things through, ask how and why. For instance once you understand HOW a MAF works you will understand WHY changing the ends or porting it is such a terrible idea.
The newbies have to sort through all this stuff and ask questions, we were all there once, it is not their questions I object too but the number of idiotic responses they recieve.
