The 3rd would be boost error correct. If it remembered the change then you're good! For some reason mine didn't so I just changed it in the definition.

Use this for the 5 speed RPM/Speed to gear table:


You may need to drastically cut WGDC during spool up for 4th and 5th to avoid over boost and the resulting high knock count. Something like this:

once i got it to have smooth wgdc application in 5th and smoothed the timing a tiny bit the spool knock went away thankfully. im inclined to leave it where it is right now since i have a track day next week and everything is working well right now. then ill have two weeks to dial in the correction tables

right now im down a little power/torque, presumably because the afr's are richened up due to hitting a new load column, but i also may have been running more boost than i thought on the stuck mbc thats been on the car since i bought it.

the test on the top of my list is gaining back some spool, it looks like i lost 4-500rpm in spool, and i feel like i should be able to cut that in half since im only running 70% wgdc from 0-4k rpm.

Yeah, tune boost by gear and use 100% WGDC as long as you can. First and second gear will be sooo much more effective doing that. This can make the difference having a weak first gear VS spinning 4 tires while having same boost target.
