Also interestingly, on another log I took the other night of a semi-pull in 2nd gear, 'Injectory Duty Bank 1' dropped from 50 to almost 0 momentarily. But I think that may be another issue altogether that Seb has said may be a failsafe map dropping the throttle, which he has adjusted and sent another tune through, I have not tested that new tune but will do tonight. See below:
Yes I did the mini pressure gauge. That is why I am taking it for a run on the dyno on Monday to see if it is holding pressure under load.
Yes I have the return kit. Well I will check the pressure under boost on the dyno, see if it is increasing. It started doing this possibly the moment I got the build done and tried my first WOT pull.
The workshop it was at, said they done a leak test accross the fuel system, tensioned all lines and could not find amy faults? |
I would verify the vacuum source to the regulator and make sure there isn’t any leaks ...you should see around 52 at idle and for every pound of boost it should increase one psi per pound ... on average.. depending on injector size a tune
May be different with e85 tho ... I’m speaking from 93 oct settings .... but either way idle should be 52 ish and it should increase with boost
