Ill going back with that, i ll take an appointment onthe dealer tomorow!
I think the pcm as been reseted or something like that.

 

also, what if the custom tune
is for 93 octane and you are
running 87 or 89

 

go to the deaker and tell them^^

 

i m on 91, i ll tell u what was

 

LOLL im really dumb!! Just find the trouble, there is a wire connection for the electronic throttle behind the plenum, guess what i missed!!!!!!!!! Now the car run like what i expected. This is my first mustang and not the last, **** that car is really powerful,i had a 350z 35th last year and i think the GT is a lot faster.

 

Sure hope you know what your doing. The PCM could really mess up your Stang if you "play" around with it. I would take her to the dealer to double check EVERTHING!!!

 

Yeah! I ll doing just to make sure, but i don t think the pcm is ****ed up.
