    I wouldn't be too fussy about getting it set absolutely bang on; it may just make the car think you're driving around slightly below sea level!
    Glad the info is helpful, it certainly helped me a lot

      So a new sensor should be set to 1200 ohms?

      I really hope it will work

        Just got back from VRS and I had a split hose which was brand new 1 month ago, leaks occur randomly and whenever they feel like it, also replaced injector seals, spark plugs, which are not even a year old with about 6k on them, and a small vacuum pipe on the fuel reg. Good news is she is now flying, happy days

          Good to hear that yours has been sorted out

          ...and by the looks of it, mine has too. 4th gear WOT ticked to 0.8 bar. As i finish work quite late, will go home on 50mph road anf see what I can squeeze outta it.

          Where can I get boost test kit, anyone knows?

                A quick boost leak test bung can be made from an empty baked bean tin and a tubeless tyre valve, then you just to be creative and find some objects the correct diameter for the other holes you need to block.

                  Yes, he came here and we did it together. But he wants to do it again to check after having done the injector seals. You fix one leak it always shows another one up

                      Because now it's boosting properly, there might be more leaks popping up.

                          Or something like this (as suggested in my boost leak testing posts):

                              4th gear got to 1.8 bar before i had to brake for traffic. I finish work at half 10 so will drive home and go on 50mph road to see what i can get.

                                Also (forgot to mention ) I did notice your WG screw was sitting level with the top of the WG. you could try screwing it down a few turns.

                                Important to check though. Run the car and check the max boost in say 3rd gear. Disconnect the WGFV (N75) and run it again, post the results. You should have approx 0.4 Bar with the N75 disconnected and approx 1.1 Bar with it connected.
