Or should I say my truck does. I think she's up to three packs a day. Accelerating from a stop or after a slow turn and accelerate she puts out a pretty good stream of smoke. Tried different throttle techniques and box on or off makes no difference. This started about 2 months ago. before then I was able to take off cleanly and smoke when I wanted. Nothing has been changed on the truck this year. Any ideas or will I have to start buying Nicorette for her.
