    Will be testing a Grand Sport with a 150 four stroke soon. Adding solid mounts, gearcase modifications and ECU program. Will do the mounts and gearcase first, and see if the ECU program lives up to the hype. Supposed 6500 to 6800 RPM, 20-25 Hp increase. We'll see.

    Wanted to get the 150 ProXS, but just couldn't get one for a long time.

    Looking forward to see the results! I assume the tuning is done by Simon? I thought he only bumped it to 6100 or 6200?
