A6 Turbo Help
Hello, I recently just bought an Audi A6 2000 2.7 Twin turbo Quattro. I was wondering how i would adjust the turbo PSI higher than factory. Also how much PSI can the turbos go up to safely and how much PSI can the engine take? I would like to at least go up 4 PSI in each turbo so i can get about 7.5 PSI out of each turbo. Thank you

Your boost is controlled by your ECU via your N75 electronic control valve. Some people have bypassed it on big turbo builds to use a (MBC) manual boost controller. Others, like myself, run the N75 in parallel with a MBC for both the smoothness of boost delivery and the option to fine tune the boost when needed but yet again, this is done mostly with upgraded turbo builds.
As far as your boost however, 7.5psi is the stock boost if I recall correctly. Most tuners run 16psi-18psi for stage 1 tunes on stock engines creating an average upgrade of 65+hp and around 90lb-ft over the stock of 250hp/258lb-ft.
If you want a basic stage 1 tune then I would recommend GTS. I have heard allot of good things about these guys lately and they are much more reasonable cost wise than most. Looks like this tune will step you up to 16psi boost for 320hp/350lb-ft. Not too shabby mate.
Stage 1 - APB / BEL

all turbos controlled mechanically..it's complicated.
Soooo, you could plumb in a T and a manual regulator before the valve and bleed off the manifold pressure signal but it's dicey without a boost gauge and like anything else if the line breaks the wastegate gets no signal and boosts without limit.
Generally a connecting rod lets go first….ask me how I know this!

Don't mean to thread highjack but I think these are relevant questions.
Good question OP!
