Air Pump used for boat anchor?
My FD has a mid-pipe. The air hose that would normally be connected to the main-cat is plugged. QUESTION: Does the Air Pump provide service for anything else in the car? If not, then i'm taking it off (to help anchor the boat for when Hurricane Claudette hits . Thanks

I've driven the car over 2k miles since the time of purchase 2 mounts ago. The Cat hose was/is plugged. Why hasn't it "coded" me since? What else is it connected to? Thanks for your advise/comments.

Removing/unplugging the air pump on the stock ECU shouldn't throw any codes (at least ones that will make the check engine light come on). However, your idle will get extremely bad and make your car want to stall. If you search through the forum, there are ways of tricking the ECU to think the air pump is still there (by using a resistor).

Mahjik: That's whats so wierd. I never had any problems associated with excessive boost. The car was bought with precat to mid pipe to HKS supper dragger muff set-up. Boost pattern was/is 10-7-10. Iv'e got the car on jacks waiting for the DP to get here for the install. Maybe then (after DP install) will I start to get the infamous "boost creep/spikes)?

Well, you are one of the very few that doesn't have a problem with it. When I was on the stock ECU, I unplugged my air pump to see where a noise was coming from... Took it on a drive and the car almost stalled twice, idle was horrible.

Yeah I think (know) I'll be buying a BC real soon.
"IF" I don't obtain excessive boost (above 12) after the DP is installed, does that mean something may be wrong with my set-up, i.e; Turbos or vacuum lines?

However, don't use fuel cut as your safety defense.

Mahjik: What is the MINIMAL cost associated with a QUALITY ECU upgrade? And will that upgrade in itself be sufficient to prevent major problems associated with excessive boost problems and engine failure? Thanks for your help and expertise.

The ECU in itself will not prevent overboosting.

Word of advice. After the dp install, watch your boost gauge like a hawk when you're WOT. I crept to 13 psi on a hot day and 15 psi on a cold day, and this was *with* a ported wastegate. I also had a tuned power fc so it wasn't a huge deal. The Boost Controller is a good purchase (I agree you should get one) but it won't do jack squat for controlling creep. Spike yes, creep no. In order to get rid of the creep you either need more exhaust restriction, a ported wastegate, or a very ginger right foot .

I'll just have to wait till the DP is installed. I'll get a better pic as to what my next steps are going to be. Thanks to ALL of you that participated!
