Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

That tells you nothing. Nada. Zilch. Get the car up to cruise speed. 55 is a great speed. Keep it STEADY at 55 with your foot BARELY on the gas just enough to keep it at speed on a flat, level surface and then take your cruise vacuum reading and write it down so you don't forget.

I forgot to add to the caption that was the cut out I was hearing, you can hear it in the video I just put the gauge in as reference to throttle. My cruise vacuum is about 18 or so that’s how I got the 9.5 PV along with where it starts to struggle.
