I run a Hypertune billet DBC one.

Supposed to give you a bit more power particularly on top.

Mine does not have an idle motor, meaning you have to keep the idle. Not ideal in a street car.

Bummer about the HP figures being identical, but hey maybe the HTZ wheel is more about quicker spool which would be even better. Can't wait to see your dyno charts.

Hate to be a debbie downer, but seems like the HTA3586 and XR7864 are nearly identical in performance! Hopefully when you get the other stuff done it'll allow the turbo to shine.

Amazing power band.

This car is the reference for a road STI. No doubt.

FP stopped making the HTA3586 and rebadge it as the XR7864, I wanted to replace the HTA86 with the same turbo

I don't know what else I could do to improve power without sacrificing spool. Upgrading the TB won't work because I would have to get rid of A/C. I could return the IM to the original configuration for the sake of fitting the TB on it but I would lose spool. Maybe I'll get KillerB headers to replace my 8 year old GTSpec headers
