of to the track this weekend and i thought id go for one last spin make sure all was ok
plugged im lm2 afr and away i went.found a little streach of motorway near me and thrash it up and down the gears.
on full load flat out in 5th i was getting readings of 10.9-11.5 on the lm2.

Firstly how accurate is your AFR reader? 10.9 is rich but 11.5 isn't too bad!

well in that case i guess you are abit rich the saph was running a t4 at 2.2 bar 472 bhp 11.3 afr, supra is running t51r 2 bar 860 bhp at 11 afr.
better a bit rich than lean though fella.
