Hi, I have a 2000 Jeep wrangler TJ 2.5L which I put a turbo on. I am reading the air fuel mixture and its running at 19.0 when it goes under acceleration which is horrible. Keep in mind I have never tuned a car before and I want to learn how to tune this car. What are some steps in proceeding forward. Also I have my credits for the vehicle, I have a MPVI3, and when I load up the scanner every box on the left is grey. I would greatly appreciate any support I could get. Thank you.
