i dunno lol.. all synthetic oils in trans and diff, i was running 93 octane.. pv2 and green performance air filter also factory tires might help.. the first takeoff was slightly downhill... i have noticed my vx loves to get the RPMs up really quick.. actually redlined the other day and the trans skipped around and backed the rpms back down to like 5500 before it would shift

oh Ldub.. do you think that the exhaust insert you used would take some of the high pitch out of the exhaust note?
