Boost cotroller for my '01 Audi S4?
Does anyone know where I can get two boost controllers for my S4? I think this will definately help my performance. I dont need anything expensive I mean, I saw on Ebay there's some universal manual ones but I wanted to see what others recommended first if anything. Thanks

Why are you getting two? Hell, I have four on my car for quadruple the boost. I'm running about 37psi on stock k03s!

Thanks for your somewhat useless input, I'm surprised no one really knew the answer so I asked the experts at www.achtuning.com. Here's what Skylar responded in case anyone else wants to know:
"You really don't want a manual boost controller,
increasing the boost levels without adjusting the ignition timing and
fuel mixture will lead to melting internal parts of that engine."
I also contacted www.audiperformancetuning.net and found out that the S4 comes equiped with its own electronic boost control valve called the N75 so a manual or electric boost control upgrade is not neccessary with any upgrades. Makes sense.
Sounds like sound advise.

yeah i knew of the n75 but you can take that out just unhhok it leave it all plugged in and put the mbc around there but make sure you leave the electrical part of the n75 in still so you do not get any check engine lights......but i have heard that it is pointless to run the mbc with k03's anyways....if you have k04's then it wrill probably be a different story......but hey check into keep us posted....

Will do, I'll post as I learn. I havea slight lag onmy take off but I'm pretty sure its a small boost leak. No biggy though, its running great. So far I've done a Front Mount IC, Bypass valve upgrades, Cold-air intake, and chip tuned it. I'm putting out about 325hp but have yet to dyno.
