There were a few other cheaper ECU tunes w/no pulley's avaliable, but buying cheaper - sometimes you get what you pay for and they were questionable. It was a brand new car and I wanted the best for it, my only chioces were RENNtech, Kleeman or Evosport. But once I found out those RENNtech badges added an 10HP, I went with RENNtech and got two sets of badges for an extra 20HP . Although there are cheaper ECU/pulley kits avaliable, I have no regrets going with RENNtech. Having an ECU/Pulley kit from a prestigious company like RENNtech is worth something .
