So I ran some 0-60mph times. Could someone look at run 2 of this log? Is it even possible that I got a sub-3 second run? Or did JB4 glitch? I realize that this isnāt as accurate as a draggy. Thanks

Yes Iām finding out that fuel source is important. Just limited in what is available close to me. So for 5k+ on this map, maybe go to not more than 4.2psi and taper to 3.0 by 7k or just keep flat?
Running a different fuel source at high altitude. Had to adjust my boost pressure down. How do these logs look? What happened to my WGDC the first pull? Thanks

Yes I already have an Evolution Racewerks 200 cell downpipe but was wondering about Leviathanās clam that āvirtually all exhaust systems reduce down to 3.15ā to connect with the factory Downpipe.ā And whether that is solved with my 4.5ā downpipe or needs a full exhaust to not limit flow?

on the first run, I increased psi at 3500 rpm to 3.7 instead of 3.6. But got boost pressure spike at the end of the curve but not on boost 2 curve.
Second run, returned to 3.6 @3500 and the spike is gone.
Third run, tried increasing psi at 4500rpm from 4.6 to 4.7 but again got pressure spike...
So boost is at chargepipe and boost 2 is at manifold. In theory boost 2 smooths spikes in pressure and is what āmattersā. So the boost curve could be a little smoother by upping the psi a few points at lower rpms?ā¦but pretty close to optimal now.
I went back and adjusted boost at 6500rpm from 3.6 up to 3.7 but got throttle correction, see graph with blue circle. That pressure spike at the end is an indication of? So Iām thinking that Iām optimized for higher rpm range.

Help me understand what is happening here at 2800-3100rpm when the throttle drops way down before maxing out. Is that a function of the turbo spooling up to speed and building boost? What is happening with the engine at this time?
