The setup it has, has ran flawlessly for 5+ years. And yes, it has a chip, rising rate FPR, big injectors, and dual -044 pumps. All else is factory FI components.
I unplugged the high-altitude switch and no change. Stills runs like crap right off idle.
Fuel pressure is running at 2.8 bar at idle and jumps quick if you stomp the throttle. What I'm not seeing is a bump in pressure if I quickly, slightly crack open the throttle. Only with large openings will the pressure jump.
Wonder if this normal?
