    So I have around 1k miles finally. I turned the boost up and went to do some logs when I found that the pressure would not go above 14psi. After some diagnosis I found that the CAT had blown apart internally and was lodged further down the exhaust causing a huge restriction. I ended up deleting the CAT temporarily and found that it has probably been partially blocked for some time because the car is WAY faster then its ever been now!

    Here is the first pull at 20 psi after addressing the CAT situation. Had to add a bunch of fuel to the top end of the map after this pull...as you can see the AFR gets way too lean at higher RPM. Its Amazing how higher flow demands more fuel LOL .

    Finnally got her on the dyno again with much better results. 431 awhp and 352 awtq @25psi on 93oct pump. Still needs some tuning. It was hitting some strange rev limit at 7500rpm even though nothing is set to that but oh well...making progress
