I'll try again tomorrow and log it as a .msl. Are .msl files able to be loaded to miataturbo.net? And what perimeters would you like me to have logged?
I can't help but think there is a lot of power still on the table. I think i'm a little rich and not enough timing. And of course about 4 more psi of boost would help.

Are you SD card datalogging? If you are using tunerstudio to datalog, it will log ALL the data unless I am mistaken. I only ever have to pick and choose when logging to SD card.
Also, you have a forged rod motor with good pistons and pump gas compression. I wouldn't stress about that motor.
Your turbo however might be choking your potential.

there is a default function that will log everything and or you can tell it to only log certain data points.
Not using a SD card, just telling tunerstudio to start and stop logging.

i haven't done the timing belt since i built the motor a few years ago. Not saying its not possible. i idle at about 900rpm and if i remember correctly at about 35kpa. I can double check this tomorrow.

I'm thinking my cam gears are off by 1 tooth each. What do ya'll think. Marks on the pulley line up with the "T" on the belt cover and matches up to where my extension stops going up.
All I can think is that if it is off by a tooth. It runs and idle remarkably well.
btw, sorry I couldn't get back to this sooner. I had to get surgery on my wrist which has prevented much wrenching.

So, i believe i got my issue figured out. I'm like 95% positive that the timing is off by exactly 10%. I starting tearing down the front of the engine to double check where my crank was sitting. I'm using the keyway instead of the half moon on the gear cause i don't want to pry the damper off. It seems that the timing marks on the supermiata damper are a little strange and one mark sits on the "T" and one is off the scale. I used this thread for reference https://www.miataturbo.net/general-m...ry-here-89510/.

Little update.
with the timing correct went to the dyno and actually pit down some reasonable numbers. 220hp and 229 ft/lb at 14-15psi. Sorry for the lack of the dyno chart. But the shop lost it somehow.
