Hey Guys,

I got a 03' F-150 4.6L V8 2x4.. anyways I put on an aftermarket exhaust, (flowmasters). However, when I did this I took off the catalytic converters. After that, I got a service engine light. I ran the codes and it came back as im running lean. So that led me to believe that my air to fuel ratio needs to be fixed. So would the Edge Evo tuner do this? I read about it on various sites and alot of people on here recommended it for the 4.6L.

Thanks for the input,

Austin

 

No, definitely not. The Edge is for a stock engine. An exaust change does not count as non stock, but removing cats, does. You need to put the cats back on or get custom tuning. You most likely need to be dynoed with the custom tuning.

 

alright, thanks for the help. hat was the other route I was going to take if te edge didn't fix it
