If you have very light throttle, you will stay in vacuum for sure.. I can be at 5,000 rpm's and stay in vacuum and maintain speed on flat ground..

it really depends on how much you step on the gas pedal. you can be at 4000 with your foot barely on the gas just cruising you willl be in vac. but while going uphill its hard not to be in boost

It goes by load not RPM. I learned that and learned how to drive out of boost. Once you drive it you'll see.
