    Air pump and low speeds

    When I am first starting off from a dead stop and not giving it a lot of gas I can hear the air pump working. It makes a distinct noise. I was wondering why does it work after the car is warmed up? Isn't supposed to feed air only when the car is not at optimal temperature?!



    depending on your answers this would be another question I would like you too keep in mind. What internally or externally could I change to get more air to the cylinder that isn't to mean on the wallet?

    You can remove the emissions equipment from our cars. Many do when installing LTs. If you have emissions testing, it probably wouldn't be a good idea.

    You could possibly have a relay sticking. I seem to recall mine doing the same - but I removed all emissions stuff a long time ago.

    And you could get the resulting SES light, from removing the emissions equipment, tuned out.

    unless you send the PCM for tuning, the removal by itself won't give you any gain.

    if you remove it the SES light will come on. It won't affect the driving but if it bugs you then you need to have a tuner disable the codes for you.

    Like Knight said if you have emission inspection is not a good idea. Check that relay, it will be an inexpensive fix if it is bad.

    I don't have emissions testing. I could run headers with no problem(as long as they don't set off car alarms)

    What would the PCM tuning do with the removal of the air pump?

    The tuning will eliminate the error code it will pick up from the lose of the emission parts. So you don't have to look at check engine light all the time and not know if an actual problem pops up.

    That's what I was going to say. Makes the car alittle lighter and cleans up the engine bay. Doesn't do anything else.

    Do you already have a tune? Are you an automatic? Do you know someone to tune it for you?

    I would recommend a Frost tune. Your car will wake up quite a bit.

    Frost is a member here who works for a company ( I don't know if he owns it or not), but feel free to contact him(them) and they can answer all your questions on what they do.

    I can tell you a bit about my experience since I have an A4. I did the frost mail tune. I email him and explained that is my DD and I will use next day delivery and will like the same back. He did my tune the same day he got it and he put it in the mail the same day. My mods were pretty basic. I tell you is well worth it just by him adjusting the shift points. You will notice that your car accelerates way faster and the throttle responds faster. It's like having a different car.

    So the best and more affordable way will be Frost mail tune. He also offers great costumer service and support.
