Works well.
I fitted this and tuned it to the recommended settings for my high compression engine in about five minutes - dead easy. The difference is very noticeable. More low down torque and better responsiveness. I have drag pipes so the torque spreads right across the rev range. I really have to punch those gears now when I open the throttle up. I will now get some new plugs and a dyno performed to get it tuned perfectly.

Power increase and great acceleration
This product has made a big difference to my detuned motor. I say detuned as my motor has bigger pistons, head and intake work. It needed more fuel and this product delivered. Just a couple of things to note when fitting. The slider has angled holes drilled in it and a couple of them had burs - easily removed with a small drill bit turned by hand. Secondly, the small spacer that rides on top of the new needle must be pressed into the part that holds it in place. If you don’t do this I suspect you’ll have issues.

It works!
Slightly different design and feel to the original, but it works well.
