i just bought 2010 jeep srt8 with American racing long headers and moper intiack and diaplo tune and its hit 0-60 in 4.7 its normal beacsoe i don't know alot about the car its normal or i can i do anther tune and do more than 4.7
I can't find much info but it seems there's different levels of altitude depending where you are in Saudi Arabia, I see it ranges from sea level up to 2000+ feets.
So if you are maybe above sea level this might be the cause.
and do u know some way to know about the headrs its amircan racing headers or anther with out i go to the workshop and the cheack engine alram some times its come how i know the warrring number
