Default Boost level and spike video of my Stage 3 APR (27 p.s.i?) LOOK INSIDE

It seems no one ever shares the exact details too often. So whe on a cruise I got this video and wanted to share it with you all. I am always curious about this kind of stuff so here it is.

It is a real short video (see link)


I have the old smaller 2.25" APR exhaust and some RS4 parts. i doubt those affect the boost flash that much. The believe the small exhaust actually hurts it. When I run open dumps at the track it spikes higher.


Specs on my car here if you don't already know my car: <a href="http://www.jaybquick.com/01Audi.htm">http://www.jaybquick.com/01Audi.htm</a><ul><li><a href="http://www.jaybquick.com/cvspeedmeets/boost%20Jay.wmv">Boost Spike</a></li></ul>

Default I don't think a quick spike like that is necessarily dangerous, but it wouldn't hurt to throw an MBC

in parallel to cap boost off around 22-23 psi, IMO.

Might want to find out *why* it's doing that first?

Default Agreed, but I've found that boost control can be very car-dependent.

Generic software that runs perfectly in one car may yeild boost spikes in another car even though there is nothing physically wrong with the car.

My guess is the Stage 3 code that he's running along with the numerous intake mods (the APR Stage 3 code certainly wasn't tuned based on the ported heads, RS4 cams, etc. that he has) is causing his initial boost to overshoot a bit. Nothing too serious.
