Dyna 2000

They are a very versatile bit of kit bud, especially for turbo and nitrous run motors mainly because they are totally adjustable, which also means get it wrong and it run like a bag of spanners.

Built in rev limiter too which is a handy thing, as I have a separate limiter on mine because I only have the early dyna set up on my engine, which is non adjustable apart from minimal adjustment on the back plate and pick-ups.

Not cheap, but a far better option for getting it right.
