well your in NM , I was going to say if the engine is not up to normal operating temps, then the ecu uses the 0 cam degree fuel map and if it s not tuned perfectly for your car it's going to shit it self. people you have to understand when winter comes in , the air and temp , as well as barometric pressure will affect your tune. so I allways tell people Get 2 tunes - one in summer and one in winter to accommodate for fuel and environmental changes. If your temp is constant year round then that's not so much of an issue.
