and issues with the little knocks on the 2nd run? All in 3rd gear
Nice car and quick Draggy times.

Accelerator pedal is 100% from about 2500 RPM but Load Target only gets to where it should be by about 3000 RPM, then overshoots, boost spikes up to nearly 19PSI.

I'd expect a Stage 1 tune to have Load Target to be at around 170 as soon as the pedal was 100%, hit 16 - 17 PSI and hold that pretty well flat through to redline. Apart from that the first run looks pretty good. I think it would get a nicer Timing transition and ramp without the boost spike.

What fuel are you using?
