skylineowners.com had a rolling road day, i wasnt going to bother putting my car on as it was on when it was tuned obviously. since then though the intake has been changed and the base timing too so i figured why not. im glad i did really as the AFR's are pretty horrendous...

when the intake cam switches at 4500rpm it goes badly lean as you can see, then the exhaust switches at 5000rpm and it comes back down again

Can you give more information on the intake and timing changes? I got a dip like that when I replaced a CAI with a POP-charger type intake. Timing advance helped remove the dip (and keep the gains at higher RPM) but I need to get back to the dyno to finish working on it.

it went from a 3" exhaust flexi pipe with injen filter to a straight 3" carbon fibre pipe with a velocity stack on and no filter. the timing had been retarted a couple.

its going back in for retune and rev limit raising to 8k pretty soon

Cool - I look forward to seeing the results of your tuning.
