Finished breaking in the engine and turned up the boost (slowly, carefully checking AFRs along the way.) Up to 19/20 psi now (18.9psi on the nemesis, ~20psi on the autometer 20psi boost gauge, who knows.)
The 46-trim spools up nice n quick. In a good launch (if I can keep from spinning tires anyway,) I'm FULLY spooled virtually before I even move forward.
After getting the boost turned up, I'm having to re-learn how to launch on this setup. The way I used to launch now just unleashes torrents of wheelspin (AWD, on 200$/each tires.) It's gonna be even harder after we actually tune my ignition map.
On a related note, the Spec Stage 3+ (note the plus sign) is an amazing clutch, and I fully recommend it for any high-power application.
