I've never seen it but I know you can't go wrong with a Dynojet kit. The kit you linked has spacers for the needle. The Dyno kit has an aftermarket needle. I'm not sure that the tip of the needle is different then the stock needle but I do know it will be easier then shims...........and is a proven product.
You could buy this kit and be the first and let everbody know how it is...............price is right.
