Just got back from a dyno shop.

Their reading is quite a bit lower than dynapack etc used in the states.. so comparing numbers wont work unfortunately. But you can see the before and after (which is more important that bragging numbers) figures here. Also increased the rpm by 200rpm

Their A/F reading is quite different than what I see from logging too, so I ignored thier A/F reading (sniffer at the exhaust tip). The car actually runs close to 12.5:1.

The car did not knock at all, and even though I wanted to run more timing up top, it was not allowing me to go any higher than 30~31deg. Tried both burntime table and VHR timing tables, they don't seem to take it any higher.

Overall 5% gain, I am happy with it. Have not played with the VVEL because I was not sure what to do with it yet. Apparently VVEL C table is what is used when WOT. Anyone wanna share VVEL tuning techniques?

I will post up the screenshots of my tune later today, and do another data logging (forgot to save the log after the tune..).
