Dinans tunes are very mild. I think their stage 2 in the states makes 230wkw and stage one only boost .9 bar which is around 210wkw if that. They have got marketing and surround there products with a lot of hype. They also use to sell there products as if it was BMW approved in the states until it came to light that Dinan carries over the warranty. The software there is around R15,000.
