I have a 2006 mustang gt auto with a CL1740 tuner. I am installing a zex kit and plan on running a 100 shot. I know I need to pull some timing I have been told about 3 degrees but the tuner seems to be in percent. how much is each percent and can i just do it in the global spark advance?

relax I had the same problem it is not the tuner or the cold air intake. I brought mine home and took it to a speed shop and founds out the plugs where burnt. replace with aftermarket plugs and have no problems. I was told some stock plugs dont last long!!!! DONT CRY GO REPLACE PLUGS!!!!

Just a update did alot of troubleshouting and found out I had a small hole in bottom side of intake tube that once I got fixed cleared codes. other club member had same problem later and his was just a loos clamp on intake so double check seals

You may laugh but check your spark plugs I jave a 2006 GT also and sounds like same problem. I took it to a localtuner and ran it on dyno and found out I had bad plugs. I didnt beleive them but put newplugs in and runs great

I did that and it still is there! I also tried the c&l racer tune(not firm shift) and it is for 91 octane still does it. I did talk to a dealer in St Louis for diablo who I am talking to about purchasing a kit for my 250 diesel and he says it may be the torque converter locking and unlocking? any ...
