A misfire causes lean spikes. Only way I would want one in a primary would be having one in each tube.
I know I don't know everything, but have been tuning EFI cars for 23 years now, and have done it both ways. I much prefer them in the collectors, at least a foot from the end.

Hi Ed. Not to steal the thread. But can you tell me how I come out of the trailer. Warm the car up. Then make a run pops and bangs all the way down the track. Check A/F/R it looks fine everything in the data logger looks normal. Make zero changes go for another pass the car runs clean not a pop or bang Picks up 2 1/2 tenths. Datalogging looks the same as the first run?. Car runs clean the rest of the day.
