Talking 0,75bar !!!!!!!!!!!

Dont even ask me how its possible, but after I installed my boost gauge, I could finally see how much I'm boosting: 0,6bar in 2nd, and 0,75bar in 3rd

And I havent even tried 4th and 5th
Not only that, but I havent got the FCD installed, and I'm not hitting fuel-cut Not that I'm complaining...

Man, the Rex is fast now

Even the S5s have a fuel-cut at 8.6psi, which is 0,62bar (correct me if I am wrong US guys). So, I should have hit fuel-cut looooong time ago even in 2nd gear....

Well guys, I just returned from a weekend at my summer house with my g/f. Had a nice time, but the most important thing is this: How much is my Rex boosting now

Well, in 4th I hit 0,8bar without even WOTing , and in 5th I finally ??? managed to hit fuel cut at 0,85bar And that is with feathering the gas pedal, because boost is rising like a F16 taking off

I really need more fuel, and the boost limit removed. So, FD pump, 850cc injectors, and reprogrammed ECU for me, as soon as my mechanic returns from his vacations
