Think back to 2006 when the gen2 came out there was little or no dyno & fuelling info available. Things have moved on a lot. I spent a lot of time & expense getting it sorted. It took a few visits to the dynocentre & at least a hundred dynoruns to get it to perform at it's best. The revisits were necessary as I kept adding/changing things.
The first time it went it was mapped at all throttle positions & rpm, this took a full day as no maps were available. The final revisit a few months later was for a remap with the following mods:
PC3
Ignition module
FCE
DNA airfilter
Modified airbox
No secondary flies & spindle
Scorpion endcan
Factory Pro velocity stacks
The full throttle runs were 147rwhp & the part throttle runs were also optimised for best power.
I didn't get it dynoed with the full Akra but it usually gains 2-3 ponies up top with a full system so you should be at about 150. Having said it's unlikely you'll see those figures in the summer, you need a cool, crisp day :-)
Now, 9 years later there's a wealth of good info & some really good maps available for all configurations. If I bought another gen2 I'd just try a couple of maps for the closest configuration & settle on the one that felt best. I'd also get the ecu reflashed.
The dynoruns are online somewhere, including the old foc-u site & FZ1oa, I'll try to find them. :-)
