I have the PMS and the LM-1 on my Kenne-Bell car. I love them both and think they have been invaluable as far as getting my setup to run right. I also have the rpm converter but have never got around to hooking it up yet. It is very possible to see your a/f ratio while driving and then adjust your pms to change what you need to. I just messed around with both of them for a couple of weeks or months, or whatever it was, on my way to work and back, and during lunch. I only ran off the road a little bit a couple of times while I was staring at the LM-1. 9 or 10 lbs. of instant boost with a five speed will get a little hairy at times if you are not concentrating on the road.
I have never had to recalibrate my LM-1, and I've had it for a year and a half or two.
