Thanks. I eventually understood, I just have never seen the vacuum even get close to idle vacuum when racing, or never noticed. Honestly, I observe my vacuum gauge mostly when i'm checking on something, like a funny vibration when I stop at the light, or to verify a miss, etc. i'll have to go for a spin in the truck and see what happens.
Thanks!!
Take care
