5x5 part-throttle ibitty jibbitty

Is it normal for the comp/ufm to make the engine run a tad rough at slight throttle positions, say less than 20-30%? I'm using the Blue Chip cover for the connection and had to re-work it once to fix an all-level roughness from the weak connection.



I've decided to splice the wire properly when I get around to it.



Levels 1-4 are smooth and silky at all foot positions, but I have to stay in or out of it on 5x5, no putting around.

No it not normal for it to do that. Check your fuel pressure. When i had my edge comp it didn't do anything like that but since i installed my TST comp on level 7 and above it does it. To my knowledge the edge comp is not aggressive enough to make anything like that happen.

FP is 10 psi or better when this happens. It's done it since I got it. I ran a full tank on 4x5 for fun and mpg with no problems. When folks say they run 5x5 all day/week/year long, I think how can they stand that?



No change with the new injectors.



So who has a boost fooler I can borrow when I send the box in for Lawrence and Keith to check out?
