Cruising AFR's
 

Is it normal for the car to hit 16.0's+ while cruising in 5th going about 65-70? It'll hit those afr's then have a little hiccup for split second then go back to normal. Car is tuned and on e85

In for a response. I'm tuned on e85 also but during cruise it'll bounce around from 13.5 to 16 but usually settle back around 14.7. Could just be injector size. I know precision tuning on big injectors takes time. But that just my opinion.
