haha sorry. Just trying everything at the moment im losing my mind.

Because i dont run a vacuum line to the fpr yet it sits at 70psi all the time. 4k isnt high rpm :P.. Ive also tried a 255 and 400 walbro's. Both doing the same thing..

There were no issues on the dyno holding 70psi using both fuel pumps all the way up to 8200.

But yeah, defintely something weird going on.

Ill get a gopro vid happening when i take it for a drive, ill try tomorow arvo.
