The manifold can hold up to 12.5psi of boost, after that your pushing it. I would get ride of the diverter valve in there if your sticking to the stock manifold. Also, the stock mapping for the MS45/MS45.1 ESU (2003.5+) will adapt to the 4.5psi.

I would start off at a lower boost and go up a soon as you get a hang of tunning. What I did was use a data logger and a Apex'i SAFC for tunning, and was going t upgrade to an E-manage ultimate. It works and the marketign scam with "You cant tune this ECU" is all Bulls**T. I have done it and it works, if you know what your doing it will work. I will post pictures of the process soon, as your request and as many others...As for another car, I have bought a new one. I''m doing some work to it, then will revile it to the forums as soon as the cosmetics are done...Ask as many questions as you need and Good luck!

thanks for the info i think i will start at 4 lbs just to start messing with tunning how did you connect the software to the cars computer did you have a wiring harnes or did you have to go in and splice into some wires this is my main consern because i have not found a wireing harness for my car was wondering if you had in pictures of this for better reference.
Did you just use a log manifold that is what i was thinking of making
As for the diverter valve what exactly is it i am thinking it is a plastic peace in the intake manifold that splits the incoming air into both banks
thanks again

you can buy the tubular ones from ebay and redo all the welds, that what I had wit hother personal modifications to the manifold. But I highly recommend buying the CAST IRON turbo manifolds wit ha external waste gate already imprinted and cut for a tial 38mm. Benefit of that is, you don't have to worry about ur manifold cracking under extreme EGT's.
