The profec is good for at least 2 to 2.5 bar if my memory serves me right. Thats 30 to 35 psi odd PSI
All that and you still have a JWT tune ECU? Is it a proper tune where they put you on a dyno or one of the "drop-in" chips? Cause you should really get a proper tune otherwise.
im go to dyno tune when My car was ready. In quebec,Is winter and my car is stored at this time...I buy this chip just for start my car.
Ah fair enough. Winter is the best time for a tune though isn't it? As in summer, air expands so you'll just be running richer if anything. But those are heavy mods you've got there. Be interesting to see what it runs on a dyno. Have you tried to start her up since the rebuild you've obviously been working on? Sounded nice? Be interesting to hear a B&B system. Are they the Labree that split all the way down or the "half-split" type?
I really want to know the real number because if is not enough. I think buy PERRIN solenoid upgrade for my profec b spec 1 http://www.perrinperformance.com/products/show/64/Boost-Control-Solenoid?category=37 With this replacement for my boost controllers solenoid, i never need more
In the product feature list it says "controls boost up to 43.5 psi" so it looks like you wont have any problems there matey
Are You sure is for PROFEC B SPEC 1 (the original) not for spec 2. If its right,Im very happy to hear this.
Your search skills need attention dude, some clown held over 700hp with one off these things, is that enough? http://www.mkiv.com/techarticles/greddy_profec_b/index.html
2 bar, 29psi Heard rumours that it doesn't hold over 20psi with much stability though. With the amount of money you've spent on your car why would you go with such an old controller? Sell it and get a Blitz ID-III. :zlove:
Winter in Canada (some places) = freezing your coolant and split your block and radiator. I expect that's why it's in storage
thanks but i like the look old school of this controller:zlove: I thinks buy the Perrin solenoid upgrade for my profec b spec one if they not hold high boost
