my truck smokes a lot between 1k-2k rpms under normal acceleration (10-40mph). is everyone elses like this or am i just throwing money out the tail pipe? i did get the recall for the 02 deal fixed last year, but i am not sure what flash it has. also had the turbo replaced early on. would a programmer help? i get about 15-16 mpg with pretty much all hwy mileage. my rear bumper is pretty black too.
