Anyone else?? > > 1 bar = 1 atmosphere = ~14.7 psi So 1.7= 0.00 vacuum + .7 bar of boost, so .7 X 14.7 = 10.29psi of boost..... Stock is 1.4/5 maximum or 6-7psi..... The 1.7 bar (assuming your guage is accurate -it's not) would be roughly 40hp over stock.... Assuming you still have a functioning WG freq valve, it's no longer adding to the boost of WG above the computer controlled limit...... So if you have a 1.7 bar spring from the charlie man, you won't get no more than that, the WG is dumping = no more boost.... Scott
