It seems like your car is really struggling to get fuel in for some reason. This probably isn't great for keeping exhaust temp down. But the load isn't too high yet in that part of the pull, so there's that. Is it normal for a ps2 to take that long to spool up? I'm still on the stocker snail.
You're referencing data points when RPM is from 1700 - 2600. Yes... you clearly are not a tuner 😂
