I have a 03 dura with the banks six gun and speed loader w/ 4" magnaflow turbo back. As soon as the temp warms up it smokes blue smoke bad at stop lights. Smells like a lot of fuel real rich. Fuel mileage and perfromance are still great. Read other posts wouldnt an injector effect the mileage and performance. I have had the injectors replaced by dealer (RECALL). 2 to 3 years ago. Banks and exhaust put on a 1 1/2 years ago.
