Thanks to Akuma for helping me get the issues with the car sorted out before the tune (there were many...) they were awesome to work with. Car was tuned for 19psi. It seems we just ran out of intercooler and anything more the car wanted to start detonating. Ill be back in the spring hopefully with a FMIC and possibly some meth and have John open it up. But given the slaughterhouse that Akuma's dyno is proving to be, I am fairly pleased with nearly 310whp at only 19psi.
Data plot shows that boost drops off, but that was an instrumentation issue, boost actually holds flat out. The car drives very well, is very streetable. the turbo is a BNR vf40 conversion to a td05/20g for 08+ wrx/lgt fitment.
Thanks to BNR for coming to the LGT guys with a turbo option, for Akuma for straightening my bad install of an absolutely ****ty perrin inlet/ic, and the guys at Broken Motorsports for the extra parts I needed day of the tune.

Looks good John, as always nice work! Any plans on a trip back to Utah? I want a protune.

Thanks. The boost curve looks a bit funky because our PCB sensor is taking a dump. Again! I ordered a new AEM for the dyno, it will be here next week. The damn sensor drops voltage abd is skewed by 1.5PSI, very annoying. Anyway, for the 5 speed this power level is close to the threshold for reliability(yes-some go for more) and on pump, the car was happy with the boost and timing, so we left it. Drives very smooth on the street.
