#138296, "RE: Car goes into open loop near 0 vacuum" In response to In response to 1
I'm running 440's w/ SFMU & Missing Link and get similar results... I would describe it as 'transitioning' from vacuum to boost. I know with my SFMU, the suggested action is to drill out the inline vacuum restrictor a little bit to allow the SFMU to act more quickly in transition. What are you using to manage fuel?
I've been putting it off, I usually just step on the gas a lil harder to get through the transition to go into boost quicker - J
