um, ive never heard of a bad idle, it will take a finer touch from the dig, and yes it does fall faster but then again go SOGI short shift and learn to do it quick (also adjustable BOV im assuming would help) and you won't lose as much on the shiftTealmetalicDream said:its a good bad buy,
Good: faster turbo spool, better acceleration, easy to replace surface face, light weight
Bad: can cost 300-400, bad idel because of the loss rotational mass, lexus afm + light weight flywheel is not a good combo. Motor will lose RPM alot more in between shfts because of of the loss of rotational mass.
But with a motor that is balanced with the lightweight flywheel on it is worth it IMO. I have had one for about a year and i love it.
the good overweighs the bad.
