I run the DS trinity.
Actually it has pissed me off a few times. I've had to overnight the PCM to them one time cuz their tuner messed up my PCM. left me immobile for almost a week, cuz they have no customer support over the weekend. got that all fixed up. running 91 tune and throttle booster, which really helps actually, and speedo cal. got worse MPG.
Then switched to 87 octane and MPG tune, with throttle boost, hard to tell a big difference between the 91 and MPG tune to be honest. and havent really seen a big difference in MPG either.
and more recently, as in 3 days ago, took it to the dealer so i put it back to stock, got done at dealer, flashed it back to MPG tune, now i have no steering wheel audio controls and my compass is no longer displayed. so they are supposedly working on a fix for this. call them up and they were clueless. so we'll see. at least it's driveable.
not sayin dont buy it, but $600 is alot for what i REALLY use it for, which is to adjust my speedo and the throttle response. that alone has woken it up a bit, gets rid of that lag off the line. but, i run with top off, doors off, doors on, top on, top on/doors off. all kinds of combos...and i've always been around 16-17 mpg with or without the tuner. So, is the thing really helping? who knows...
runnin 35" falken rocky mountain ATS, 3.73 gears, auto. BTW.
no noticeable 'OMG' fuel mileage increase.
trans still shifts funny like it always has. kinda half shifts or somethin between 2nd and 3rd gear...pisses me off. but, guess i just live with it. kinda scared to mess with the tunes any more cuz of it messin my PCM up. but, they did fix it. just sayin...its a PITA to have to deal with.
