Just got back from the 6,000 mile service/DPS update. 60 mile ride home and I kept waiting for any sign of surges, pops, hesitation, etc. Mostly freeway, but also had several miles of city streets. Ran just as good after as it did before. For those who have had problems, was it immediate or did it show up over time? I have stock pipe, no JB or purge valve mods. Regarding the steering fix itself, I paid really close attention to steering input and response on the trip over and five hours later tried to "feel" any difference. Maybe just in my head, but steering seemed more precise and less twitchy.
