troubleshooting see the video of the odd high pitched noise here, https://photos.app.goo.gl/F5cdWwwM1syvTqPm6
seems like the problem lays with injector 2, no plugs were wet when I pulled them on cold start. inj 1 and 2 were not fully seated, so that was quickly fixed. Any potential for damage to the sealing rings in there?

troubleshooting hunting down issues while at wot in second gear. the vehicle pulls until 5k+rpm, where it then gains misfires in cyl 1 and 2. this issue has been happening from day one, potentially a vac leak somewhere in there. next step is bypassing the oil catch can and setting the pcv to run directly to intake. when misfires happened, a loud noise akin to a long beep would occur coming from the engine bay. the vac canisters are bypassed to reduce vac leak possibility.
replaced spark plugs, coils, injectors.

Version 1, base tune Cutting it and going into limp mode on wot. Totally kills power until I chest choices, then all is good.
I did also play with the mhd stage 2+ tune, and that does work but there is a slight misfire. Not big enough to throw a code apparently, but it's there.
