Red loctite is some very serious stuff though. I assembled a 13b eccentric hub with red loctite, and absolutely destroyed a Snap-on 19mm impact socket trying to remove the hub bolt. I can only imagine what it'll do to a .25" turbine shaft if I ever have to disassemble it
Thanks for coming down to Jax. Glad to see the turbo is still holding together. Ever figure out that TPS issue?

Well, I have the acceleration mode set up to only take inputs from the MAP sensor, and it's been like that the whole time. I don't think the TPS has any other function or input to the fuel map except for accel (TPSdot). I just figured out MegaTune's datalogging feature, so I'm working on getting some logs of its funky idle and jerky cruising habits. Other than that, it pulls just fine at full throttle, so I know the base fuel map is good, I just have to get the idle and cruising under control. After all that's taken care of, I'll troubleshoot the TPS to see if I can get a smoother transition. Although, it's not going to be that noticeable with the S4 narrow range TPS anyways, but I still want to give it a shot.

I really enjoyed the meet, thanks for putting it all together. I hope to be able to go again if it gets back together but I may not be able to go to the next one, depending on when it is and when I go out on deployment again. I sure would love to see some more 2nd gen love there though, kind of weird being outnumbered by FDs and FEs for once
