Milford. I ran 250/200s with my 471. It was all around a very nice setup. You will pick up a touch more top end, but you will sacrifice a bit of bottom end and response.
Oscs. Its not that the did a bad job, hell I liked their tunes but when I brought to their attention that my truck idled perfectly fine with my old tunes and with yours not so good, and noticed that tuner A ran 700rpm and 625 icp and it idled nice and tuner b idled at 650 and 800 icp and idled like a POS without even trying to update the tunes I was told by his partner that my injectors were on the way out. Keep in mind they had less then 5000 miles on the whole motor and sticks. And my old tunes ran fine
Its too bad, to be honest if they had fixed the idle I would have most likely passed on Cales live tuning. So I guess in the end it worked out well because not so much for the tuning but Cale got my PCS issue sorted and wrote me a badass trans tune.
And the tunes as well, even after a new set of sticks from Nate, gen3 and a new s475 those tunes don't idle for chit. and Cales idle good as do Matts.
My Swamps tunes ran great, however being told "I am to believe you have injector issues, so we are refusing to tune via email." Really rubbed me the wrong way without even attempting to adjust the idle.
