I finished up the fuel system as well as the turbo replacement in the 06 GTO. In 3rd gear it spools to target (about 11psi) around 3200rpm, which is about 250 rpm slower than with the smaller .64A/R housings.(now .86A/R) 4th Gear spools around 2800rpm.

1st, 2nd, and 3rd are still limited by the lack of available traction.

Next up is the enable flex fuel and switch to E85.
