[quote=belew01]Yep, it's a 93 octane tune. I don't know the exact A/F tuning, but I do know he said when I got there I was running pretty lean. Now with the engine code it says I'm too rich. The shop tells me its the O2 sensors reading the extra fuel and they are going to send me a tune via email to kill the engine codes.

Dear Belew01,

I had the same problem with my car and the dyno tuner who tried to tune my car...

He worked on my car for 4 hours but could not fix the CEL light from coming on...

Then I called JDM Engineering and talked to Jim Jr. about my problem...

He suggested that I send the tuner to him so that he could write a program and load it into my tuner...

Got the tuner back, loaded the tune into my car...

Car runs great, more power and no CEL Light...

Save yourself some grief and call Jim Jr. @ 1-732-780-0770...

Dave
