JLT Series 3 Tune
Posted: Thu Jun 26, 2014 9:42 pm
I know this gets asked a lot and I'm sorry for staring a new thread but when I posted in an old topic I didn't get a response. have an 05 Mustang GT with a JLT 3 cold air intake on it. I'm running the preloaded JLT Cold Air tune in my 7140 and it's throwing the P0171 and P0174 lean codes. And here is my last written tune attached. Thank you!
