I couldnt get the tester to work (I posted about it on the thread you originally started i think). It seemed like air was getting past the TB as well as back out of the inlet pipe where the tester was clamped. I am not 100% sure, but as i mentioned in the Oring thread, i completely removed and reinstalled IC+CP using the larger Orings, double checking all connections, etc. Unless the IC itself it leaking... i reget not trying to pressurize that when i had it off. I just cant see any logical point where things can leak now.

Also, i did logs after installing the IC+CP but before flashing and the boost looked almost identical to before i installed the IC+CP:

100% stock:https://datazap.me/u/thejeremyman9/s...=0&data=4-5-19

stock tune, IC+CP installed: https://datazap.me/u/thejeremyman9/s...=0&data=4-5-20

Yes, boost is lower than stage 1, but i thought i would see signs of a leak right away.

Also, i'm pretty sure you posted in other threads, including the MHD one, about high WGDC concerns for stage 1 flash. Your logs looked very similar to mine but you were a little closer to boost targets. Did you end up finding a leak? I couldnt really find many other MHD stage 1 tunes to compare mine to.
