Just a quick question;

If I get my throttle body ported, then the computer will detect more airflow and compensate with more fuel - correct? If so, will that make the 02 sensors (or some other sensor) freak out a little and counter that result?
Its an 05 coupe, non zo6, A4, Halltech CAI, B&B cat back exh.

Thanks in advance

No problems at all will be encountered ....the ECM has plenty of room to compensate for a ported throttle body .... but on a stock car you will not see any gain .....put the money towards a intake manifold or headers ....

Won't see peak power gains, but a ported TB can show gains on throttle response and how the car drives if that is what you are after. If it is just more power, then skip it.

Yes, thats all I'm looking for is some throttle response.

Thanks for all the responses.

you want throttle response get a good tune,

Or a Vitesse throttle controller.

Yep, GM played with the inlet shape of the TB to get a good flow balance around the entire vain movement percentage openings.


With some porting, the flow is not longer even close to linear across the vain's travel positions, making the car much harder to drive in actual street type driving conditions (semi turning the TB into more of an on/off switch instead).


Hence before you go to have a TB ported, have them print out a flow chart of the TB flow volumes through the vain's opening percentages, then another flow chart of throttle percentages after it ported. In oem, the flow is pretty linear with the different TB vain positions, while in the ported TB, no very linear isntead.

Get the V-Max throttle body and you will love the throttle response a lot of different then stock....A cheap mod.

This guy has some on his home page at the bottom. From what I understand this guy is one the best in the midwest.

You won’t see noteable power gains but the throttle response is very nice!
