You're almost out of injector anyway.

Taper boost.

If you aren't willing to do that, ramp DRL up so flat wg req results in flat boost.

Also, fix your overshoot after ramp. IMX is an incomprehensible mess during spool.

How do you assume that? maximum injection time is 16ms in the logs.
I tried many times to tune KFLDR but it gave more worse results then keeping it in stock.

I am adding two maps.

Follow the input to the map and figure out what cells are being used during spool.

The ridiculous curve is immediately obvious.

"Left drl stock" "fucked up dimx"

Understand the input to the DRL map and bingo... you should find your problem
