will ported TB mess up tuning?

It will alter things a bit. I've had my car tuned and have changed the exhaust setup to true duals, have put on a ported TB and things are a bit wacky at startup. Engine needs about 3-4 minutes to find itself and run correctly. After that, things are fine.

Maybe you're thinking the ported MAF, which is
probably the single biggest sexually transmitted
disease of the late-model F-body.
The TB is basically a piece of pipe, a ported TB
is a smoother piece of pipe, and if it doesn't leak,
it can't affect the mixture (though it could let
you intake more air at high RPMs, attaining higher
peak cylinder pressure, and letting you ping in
places you could barely get to before).

To answer your question, the only way the TB could possibly hurt your mixture is if your dyno tune is on the verge of super lean already. The MAF will read more incoming air, therefore adding the proper fuel to make things right. You should have no problems at all.

Some TB's are epoxy filled and alter the idle air passage slightly. When you're runnin' a big cam something like that can change things a bit. Nothing major, but it does have an impact.

maybe you should try a jantzer TB. Got mine in the other day powder coated red and it looked great. Very satisfied with it.

is a ported throttle body on a stock tune bad? read that in car craft magazine i think, i was just wondering how true that was. also, what is the difference in a jantzer or bauer and a home ported throttle body?
