Super 4 VTEC Not working

[One Too Many]

Hi fellow S4 riders out there. Am facing a significant issue with my S4 Revo 2010.

Unable to activate the VTEC at 7000rpm+ (no matter how high the rpm kicks)

Have done the following but issue not yet resolved. I want to seek some opinion based on either knowledge or experience. Any advise will be greatly appreciates? So please contribue and assist!

I have sought advise from a few workshops already, but all of them are suggesting different things. So I am stuck.

The following has been done regarding this issue but to no avail.

1)Changed the VTEC solenoid

2) Vacuum sync

3) Changed throttle body set

 

Please help
