You realize hes probably not going to be able to just email you right away with a tune. It will take several days to tweak a map to your cars needs, and like ive said the whole time, you are going to need a wideband to log those values too. It will take at least 5 or so reflashes to get it close to what you need, and you need those AFRs to make sure your not leaning out big time.

I would either take it into a dyno and have someone physically look at the car, or at least have someone qualified to work on it look at it after the tune. 850 miles of lean driving on a motor that has already seen a little bit of a beating = death...

 

Yeah plus I found out Mellon wants 350 for a E-tune, when I can get a Dyno tune for 290....

So I might just do the dyno this weekend. Without a wideband, can they still tune it right with a dyno tune??

 

Most shops that dynotune have their own wideband set-up. Try to make it by any exhaust shop to get an o2 sensor welded on with a plug in it and the tuning shop will use that for their wideband.

 

Good call. 05blue8, yet another reason to choose the dyno route.
