All the dyno runs I have seen for it show very good AFR's. But, they had stock headers. Do you think the other AFR's are a mess because they are running an O2 sim? I havent heard of a 7th injector for the 4.0's.
Oh, Welcome to TW!
The 02 sim has nothing to do with the front afr sensors. The 02 sim tricks the rear 02's in the Y-pipe, which do not affect AFR
As for the 7th injector, I hadn't heard of it either...Gadget from URD was the guy helping him fix his terrible afr.
Sorry if I came on to strong, I just couldnt believe you said the AFR's were perfect after the flash. Not one single person has had 11.0 AFR....stock or modified after the s/c. I think the closest was 11.7 in which case you would still want to get tuned just to be safe.
So if you know someone that was lucky enough to have 11.0, I would be surprised.
I'm going to tune my truck soon. Just got the URD 2.825 Pulley and Mapecu2. Hoping to gain quite a bit of hp
