I know there has been numerous posts recently in regards to the benefits of having the re-flash (TSB 18-037-04) done and I was all set to do it just in hopes of getting a bit better mileage. I have been a bit nervous about having this work done as I have not really experienced the white smoke issue and my mileage has been fairly good (18. 5 mpg and 12. 5 towing 13,000 #'s). I was wondering if anyone else with aftermarket injectors has had the reflash and whether you would recommend having this work done.
