I let off at 7044 RPM. Temp outside was about 82 degrees. I didn't bother with logging o2's. I think I need to add some fuel from 4000 RPM to about 6000 RPM. What do you guys think? I wasn't spraying nitrous on that run either. Thanks for any advice!

Looks like your spooling super late, did you punch it at 2500?

Well.... I tried my best to. I was kinda thinking the same thing. I'm gonna try another run again tomorrow and see for sure. Surely my cams wouldn't be causing such a late spool would they? I mean since they more or less moved my power band up a little. Thanks for any advice.

You look lean in the mid forsure. Next time give us a log with 02 as well.

Try logging airflow. That will give you a heads up on what airflow/timing map your in..

Ok fellas I'm finally back now that it's been a week later, sorry about that. My first run was actually at 18 psi and falling to 17 psi by redline, and "Not" 20 psi like I had previously stated in the thread. Sorry for the mis-info, I thought I was running 20 psi but that wasn't the case. Anyways... I went and did another run friday night running the same boost, which was 18 psi. I'm having a problem with my logger registering o2's for some reason and It's pissing me off! So here is how the run went. I'm also noticing that I'm getting a little bit of a high end mis-fire, or hesitation problem up top as well. Let me know what you guys think. Thanks for any advice!

Looks good to me, I would tune it to 20psi.

Yeah thanks, that's what I was thinking. I also forgot to mention that I have bumped up my base fuel pressure to around 47 psi. I think I'm going to try and do a log at the same boost setting while spraying the 75 shot the next time, and see what happens then. I will keep you guys posted on my log. Thanks!
