Those tail pipe sniffers are not the most accurate readings. Its best to have a wideband o2 sensor before the primary cats. Any other way is a waste of time IMO.

yeah i agree sniffers are pretty shitty, but i didnt want those "honda kids" messin with my shit i juss wanted to be in and out..
is that "choppyness" normal as the rpm's increase? also i heard alot of people dont dyno in the winter, could that be another reason for the low numbers?
