Ken,

1) Tuning of AFR was tuned at 14 AFR at idle using my HKS Knock Amp and was tuned to 11.2 at WOT. Boost was set to max at 0.95 bar as mentioned. With a bigger intercooler and more air, AFR would not have been stock!!

2) The new tune has moved the boost to 18psi or 1.22bar according to the virtual dyno.

3) Virtual dyno at 3rd gear and torque at almost 500Nm is way off and for a non-forged engine to boost at more than 1.2bar is not what I would boost the car at.

4) My power run was done in 4th gear comparing it to 3rd gear virtual dyno, might as well use an iphone app!

Below is AFR of Stock rom -- pls see. Someone has used my tune and added more boost while using virtual dyno with no knock sensing or dyno facilities, so I suppose he could fine tune the car driving at WOT at 5500rpm accurately while reading AFRs and punching in numbers accurately through logging.

Below is AFR open loop in stock ROM:
