Hmm. I've watched Mike's video, but wasn't really trying too hard to let it sink in, because I knew I was going to come back to it.

I think I recall him saying the idea of it was to polish the tune, but didn't really remember if leaving in CL was okay/not okay/bad idea/etc. Also - have you tried running HPTuners at the same time? I've been dubious of this because it seems like I'm already at the channel-limit in my SCANNER, but didn't know if running the REFLEX in CL, while datalogging, would work.

Also - have you been monitoring your LOW SIDE pressures and such? I THINK I'm finally turning a corner with mine. I can't see why I'd be running out of fuel, and I'm probably overlooking/misinterpreting something, but after seeming like I was getting large pressure swings, after the DSX kicked-in, largely smoothed out, I'm still dealing with LOW SIDE pressure dropping off at the high-end. Maybe fueling still needs to be added, but I could make more than a few hits, and have most look good, then have one that seems like it's going a few percent lean, and that's when it seems like LOW SIDE pressure drops; so it appears when LOW SIDE pressure drops up there, I start going slightly lean. I can see pressure fall as low as upper 50s to lower 60s in these cases. My last tune, yesterday, kept pressures in the mid-to-upper 60s, for all the hits, but I had to crank up pressures to near 80-psi, and ramp the OEM LPFP in a little more. I'm only running 60-pounders, but, while I don't believe I SHOULD be near their limit, the way I'm interpreting the data seems to suggest that. I'm probably wrong.

I as just curious if you've noticed anything with your pressures after your last batch of changes.
