    The psi is directly proportional to the engines rpms. What rpms are you turning?... Ron

    I don't know about a Riva reflash, but the Riva X ecu will raise the rev limiter to 8600, the Rotax Racing to 8800. Either way you would need to upgrade your valvetrain so you don't get valve float. Between the two, I like the Rotax Racing better due to the additional rpms to gain more boost.
