congrats on the project. I hope it keeps going good, and you can keep happy.
My advice. Feel satisfied once you are happy, and ignore people here saying "more power! more boost! Dyno!" etc. Just get it how you want it, and then have fun in the car!

So as it turns out when I took my first trip my wastegate was acedentilly set at 13psi, but I only seen 5 psi, turns out I had alot of boost leaks, so I figured it was my luck.
anyways I found all the leaks sealed everything, I think, there was this other wired sound when I presureized the system i hear a leaking sound from the motor or exhuast, just can't tell, I figured this must be the fuel jets. anyways I put in the fd spark plugs took for another spin, once again the max I see is 5psi, I keep trying to figure this out,
is there something more to this mystious leak?
bad boost gauge?, it came with a funny restricter T but I just took the signal right from the intake maniflod, where the two nipples are. one goes to boost gauge, the other goes to BOV
Or does MazdaManiac have a tune that restricts it to 5psi?
I want to be able to make it for this Tuesdays tuning event

Original Turbo 'd Auto !!
here is a a thought.
Seafoam the car. Let sit, and start car. Its a very good exhaust leak finder because of the white smoke it produces. I found a small leak between the DP and turbine this way. Also if you have either a puddle under the exhaust manifold or a long narrow (1 1/2") wide spray patten after romping the throttle under the exhaust mani, your mani is either not tight enough, improperly torqued or you gasket is leaking. I found this out too.

yeah it is running im working with kane on the tuning. we are messing with wot at ~4.5 psi and EBC zeroed out (EBC is doing nothing at the moment). I have the EBC to help gain spool time and the option to change psi with ease rather then be set. ill pry run just port c ~6psi and is the EBC from there up to 10-12. I will be doing dyno tuning along with EBC tuning here soon.

I Lol at the docter comment, the link to that tool is very useful, sadly I don't have one, but I have used one before, great suggestion
09facter,
thank you for you suggestion of an exhaust leak, I found one right at the turbo, and after tweaking the wastgate's preload (thanks to bumblebee) I was able to get 10psi briefly as the wastegate opened to taper to 8psi, witch for now feels good to start tuning with. I keep forgetting as well that I have a given pressure drop on the intercooler too, silly me
I did some data logs tonight and plan to submit them, wish the live tuning event would happen sooner
car feels great, I am excited to see what she will be fully tuned!!!!
