misfire issues
misfire issues I'm trying to track down some misfire issues and was hoping y'all could take a look at my tune that I got from my tuner and let me know if y'all see anything off the wall. Mods in sig. Thanks a lot.

There is nothing in that tune to cause your car to misfire. Can you even imagine how BAD a tune would have to be to cause a misfire? I'm accused of it occasionally with a mail order while an owner searches for his issue (you know, everyone's car is PERFECT so it MUST be the tune...).
Unless you force OL and 9:1 AFR at light throttle, how else can a tune even make a car misfire? Even then, I'd guess it to be plug fouling that would lead to misfire vs the mixture itself.

OK thanks. I really have no idea about the tuning aspect of it but people kept telling me that it sounded like my tune so I thought I'd have someone else look at it and let me know what they thought. Thanks again.
These are the readings I got off the coils. I think they are in Mega Ohms. Front indicates the front of the engine. The left column is therefore the drivers side and the right column is the passenger side.
---front----
.070 .068
.065 .073
.083 .079
.069 .074
So what range are these things supposed to fall in?
