Bill I'm in about the same boat as you. I've used a FAST wideband which I don't recommend to anybody but that's besides the point. I had it located in the collector right after the four tubes merge. The reading where so erratic going down track you couldn't really get ahold of what was happening. Now again this was just a live reading and not a recorded run to review it after the fact. I've talked to a few NMRA Hot Street guys that use the racepak and they are all very happy with the accuracy of the readings and if I remember right with the RP there is a way to average the reading from start to finish through the run and I don't recall exactly where their sensors was located. I think Tom's got a good idea there. Put a bung in each tube and move it around to fine the cylinder thats the leanest and tune off of that more less.

Now I think my readings on mine would have probably been better if I had a true megaphone/merge collector instead of the big Hookers collector. I think it was mixing in fresh air and making the readings all over the place.
