You have to remove your rear seat to access it and afaik only one outfit in the US have an uprated version.

sorry cant remember how much it was, but its only a half hour job to change, hardest part is getting the rear seats out!

Did you actually log the lpfp output pressure over the rev range before coming to that conclusion?

log block 103.

5 bar seems to be constantly mentioned over the internet but I think if you can maintain 4.5 bar minimum over the entire rev range then you should be supplying enough petrol to the fuel rail.

There is one other lpfp option.  I can do an intank Bosch 044 upgrade.  It will hold 6 bar at 7.5k with a 3076 so its more than good for the job.

Don't forget that your standard fuel filter is only rated to 6.4bar  :happy2:
