I would want one with an analog gauge that I could actually read. Those digitals just give you not enough, too much and in the middle and thats it. I tried one when I first got my motor running but I run open headers. The thing would blip lean every time the motor hit because of no back pressure I guess. It did kind of get me in the ball park though on my idles and primaries because I had no clue where to start. After that I took mine out to the quarter mile dyno's. It would be better to just go to some place and get on a dyno for a few pulls to get it dialed in.
An EGT sensor would be best for a hot rod.
