AMC 360 tunes
#1 · March 6, 2023, 10:06 pm
Hey y'all, I've been fighting somethin fierce with getting my 4bbl 400 to run right. I'm hoping someone might have a tune they'd be willing to share. If not I would really appreciate help dialing it in from somebody. I have no power to climb a hill at 55, my unit isn't following my afr targets, and vacuum disappears beyond 0 at 25% throttle.
Thanks in advance

Look at it this way. If you had a carb on your engine how would you look at these issues? Vacuum loss is not due to the Fitech or carb.

Ok, I suppose I'm less concerned with the vac as I am with everything else, it ran fine at one point with the fitech but after going down for maintenance it's been back to poor performance.

Check your fuel pressure and fuel filters
