I had my second update done yesterday, in Worthington, MN. I am not sure this one has anything to do with the DPS, but I think this update has more to do with the way the engine performs. Like Scotty said, "Some folks did have performance problems after that update, because it contained additional tweaks unrelated to the steering issue" . I drove home after the update, with my purge valve still "bypassed". So today I will put the purge canister back to the original configeration, and install the new vent line.
I will check on how well it performs, but where I noticed my previous problems, was at a higher operating temp and 3000 to 4000 RPMs. Now I don't have the higher temp around here. (Northern Iowa)
Driving home I had three bars, but mostly two.
