Basics of Pcv vacuum for Fuel vaporizer

I see many are promoting vaporizers and have used myself with success.

One thing to note about the average user-- the vacuum is inversely proportional to the opening of the butterfly .
This being noted :
No foot on accelerator equates to max Vacuum.
Full acceleration-foot flat equates to low vacuum.

This means max vapor is being sucked in while idle and lowest when full throttle.

Has anyone use vapor in only cruise mode - manual or other - or made a way to inversely correct the relationship .

One could use a variable pump that can be controlled by an arduino or similar to monitor the vacuum.

Please share your ideas.
Thanks in advance
Brad

Actually no you get the hugest vaccum when cruising down the road.
At idle typically you should expect to see around 13 to 15 inches of Hg. Cruising down the road with a light engine load you can see 18 to 22 inches of Hg.
Letting off the gas while rolling along can give over 25 inches of Hg.

Otherwise I'm pretty sure fuel vaporizers don't work.
