Nice results. I personally expected a little bit more at 25psi, more like 450, but you can turn it up anytime you want. Congrats!
What is peak timing like?

Do you feel that rapid rise in torque at 3700 all that much?

spool looks pretty favorable on the "big" 7163 compared to the 6xxx range, NICE

Proper power! And yeah I'm sure conservative is an understatement for that size turbo at that much boost. Single digit timing?
I also love that he revved it out all the way, interesting to see it nose over after 7, probably head/cams/IM starting to choke.

I can verify timing this afternoon, but I would agree that the dive after 7k ish is deff head/cams related as the head only has mild porting done and the cams are completely stock with non adjustable cam gears. Overall I'm super happy with the results, I wasn't shooting for the moon power wise, just wanted something reliable and streetable.

Great numbers, I bet that thing turns some heads when you get into it. Are you happy with the power level, would you want more?

For the time being I am definitely happy with the power level, but I also haven't gotten used to it yet to say id be happy here long term. I also want to avoid the "more" trap that ends up ruining a once enjoyable car, been there too many times so if I can avoid is with the Miata then I will be a happy camper.
