Its good. Buy it and do a dyno before and after.

 

Excellent find!!! Can you try it out for us please??

A couple of people have already purchased them and will be posting up dyno results etc.

 

I'll buy it if third part dyno tests show a gain. Hoping for a review/test soon.

 

I might have read somewhere in those threads that the ECU will be hard to trick and so it will reset the mapping over time and so you'll have to drive it 80+ miles again to get it flashed. So it's a cycle and not a permanent flash once it's connected.
