Message: [QUOTE="Lt.Dan, post: 1540906, member: 24137"] I've been reading this thread and just wanted to step in and give my .02 (even though I dont know a WHOLE lot about this subject).. I've had Swamps tunes for a while, and I finally got reason that a "stutter" at freeway speeds was caused by the tuning. So I decided to buy Brian's tunes just after his Black Friday sale ended (of course lol). Now Dave at Swamps told me his software did not allow him to modify the shift strategy, so I was stuck with the stock strategy (which the stock strategy on DPC-202 and MIF6 is absolute garbage from what I hear). But after I bought my DieselSite trans, Bob Riley offered to give me tunes to help with the shifting, and Dave sent me the unencrypted tunes for Bob to tweak. He got it pretty good, but it was still never great, as Bob isn't a dedicated tuner. Now I have Brian's tuning, I was thoroughly impressed, with both the engine and trans side. The engine side made more power, smoother power curve, and better pedal feel. The trans side he almost nailed the first try, other than shift points (1->2 being too late for my liking, as well as 3->4), the shift was firm, and quick, while not harsh, or lazy, and no flares so far. So maybe hes learned a thing or two lately. Another thing I'd like to add, is the whole time I'm reading, I'm thinking about how I used to have to tune Nissan Titans (I know, sacrilege to some of you, but they are great trucks). We used software called Uprev, and you would plug the OBD2 port into a laptop and do some Data Logging while on the road. Some WOT runs and driving around town, then you would send it to the tuner and he would make you a custom map. You would do this a few times back and forth until the tuner deemed it acceptable. This got the tune within 95% of a live tune because the tuner got to see REAL world results from what the truck was doing, It just took some time. Why do we not have this option? [/QUOTE]
