    The hose fits tight but the clamp is just a hair too big for the pipe so I ordered new clamps

          Yes, your clamps should solve the major problems. And allow you to accurately diagnose any others you may have.

            I just got my b6t motor running in my car with a 255 fuel pump and if it is lower on gas my fuel pump sucked the tank dry and it fell on its face for a second and then ran good again. I filled mine up and it solved the problem. Just something to try

              ^ that's a sign of a need to lift your pump up about 1/4" or dent the tank... the area around the sump pickup is too close to the surface to allow the fuel to fill the area fast enough when the depth doesn't provide enough pressure to do it via gravity.

              Slayer, try pushing the tank down or the punp up in the sump area and retest.

                I think mail still should have shipped today so I could have my clamps

                    New clamps installed. Boost leak is fixed, same problem.

                    Anything more than partial throttle and the car leans out and falls onto its face

                      What's your fuel pressure? Do you have a real rising rate 1:1 regulator?

                        B6T should already have the proper regulator. I think a fuel pressure test is in order though.

                          Just going off my dsm knowledge. Which is nothing to sneaze at.......with a 255 pump in the car. The stock regulator can't handle that much flow......regardless putting a gauge on there is a good idea.

                            Also. How are your spark plugs and wires? Are gapped correctly?

                              Put the stock injectors back for now? Whenever I have a problem I try to undo whatever I did.

                                I replaced the regulator with an oem regulator and I haven't checked fuel pressure but I will asap. If it is low what could the problem be? New spark plugs, didn't check gap and I have new 8mm Taylor wires
