I just changed the turbo and a few adjustments to the gate to stop it humping, on my sons 2004 T ute. On the 6758 it was set to 204rwkw and 785Nm same fuel no changes it did 217rwkw and 815Nm. but all 100 to 150 rpm later. Driving it i couldn't tell the difference even off idle spool and driveability. It didn't blow off the recirc valve or i didn't notice it still made a racket from the snorkel which is normal from a efr. I have my doubts if it would work on less fuel but for this power tune its pretty good and would be a lot better than this had i played with pump tune. i am positive i could get it to spool the same as a 6758.with more early torque. AFR on the 6758 is at 16 to 17 highest and never see 650C pre turbo. The 7163 picked up the afr's to 17 to 18.5 highest. I would chuck a bit of smoke off idle with 14 to 15 to get 6758 off idle spool. Also emp:imp was all lower than 1.1:1 btw and egt was never above 600C after each dyno run pre turbo.
