Just to a top gear test to see if it slips. I believe it is the clutch.

 

no,, I don't smell anything funky.. I know what a clutch smells like.. lol.. I had one go out in my friends once and when you switch gears it would go high in RPMS.. but this goes up and down in RPMS.. but not drastically just 1k or 2k and those smoothes out..

 

if you think your tune is causeing that you need to stop what your doing and contact 4ws!
