Default Vtec kicking in and redline funny!?!?!

I have a civic hatch with a b16a2 in it and recently I have noticed sometime the vtec doesn't kick in til gone 6000rpm, usually 5700rpm.
And should redline at 8500, but one day this week it tried to redline at 7500rpm....I have no idea why.

I thought it may be the ect sensor..changed this but still no difference.

Help needed its driven me insane
