the redrocket is not running correct now
i went to karns open house today and it did a clean dyno pull and on the second pull if fell on its face lean (the operator was watching my wego display and shut it down.
so i had a 30mi ride home i limped it on.
it is real flakey below 4000 rpms and will sometimes run ok from a light but it was bouncing around the afr from a 10.9 to 1 shutter to 11.5 at highway speeds.
it got worse going faster of bouncing around.
pin it from a go in 3rd like a dyno pull it hits 16.5 to 1 and you feel it lay down before it pops.
something is up.
i have been chacing a lean hot start i still may think it may be the fuel pressure regulator.
but last time it ran stupid i changed the MAP sensor since i am logging that channel also and it has twice the load on it.
anyone ever get a new factory pressure regulator ever?
the clean pull was quite lean at 14.1 to 1 it seems
.
i am told i still won again but i left horse power on the table again dam it.
