So Day 1, fully colour coded, fully cleaned and decontaminated, and TRS STG1 Software.
It responded well for 121k, hitting 97% of its torque target unadapted, so a shade under 350nm, peak MAF putting it around 145bhp. We had some headroom so added a little more fuel lower down to help with spool and response, which seems to have done the trick.
Next up, front bumper is coming off for a repair and repaint.
