NA guys have switched to Ecutek from Uprev and gained power across the whole band. I don't personally have any Uprev experience, but Johnny (JTRAN) was telling me it is pretty much superior in every single way (And he tunes both products). If you're going to pay for a new tune, there is no reason not to spend the extra few bucks for an Ecutek license.
