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?
yep i see the same thing.

Also, what version are you running? i used to get boost spikes, but v2.0 fixed it for me.

You also have some timing pull on cyl 1. My logs show the same thing. I tried regapping my stock plugs to 0.022" and it helped. You can also try getting fuel from a different gas station to see if the one you used is just lower quality.
