I've been using 4 low some lately to get the shifts in adapted now that I have the other bugs worked out. I've noticed though that once i take it out of 4 low it has virtually no power to it, feels a bit weaker than stock actually even on my big tune. Shut it off and it will go back to normal and roal the coal again. Has anybody else encountered this? I haven't seen anything in the tuning that would cause this to happen after I'm out of 4X4. It's not a big deal, just more of a nuisance than anything.
