Eric - about how much to bump up the rev limiter on a stock 2004 250 EFI?

[Simon]

I can move the limiter and lighten the flywheel for 750.00.

[merctech5591]

what would be a safe rpm range for the 300xs.. have you done any testing with them?

[Simon]

They wake up with a lighter flywheel and the limiter moved to 6800.

Would an upgraded ecu on a 2001 300X make my motor idle any better? Any better performance other than the rev limiter? Thanks!
