I dd the KEM 275 and love it. Power everywhere but still very well mannered for around town. I would recommend going with it and if there is something that you want changed about the tune Mike will take care of it pretty quick.

I got a kem tune next week after I installed Spartan. my tranny felt like it was gonna blow up during shifts and couldn't take it anymore Paid for my 250 tune and 30 mins later had it on my emails inbox. Kem tune shifts just like driving in a stock mode and I couldn't be more happy.

The whole tranny adapt thing is bunch of bull**** too, just ask mike. Our trannys are always adapting to your driving. How does 275 differ from 250 tune in drivability and performance?

Ive only ran the 250 a few times but but there is a big difference when going to the 275. I havent ran the 250 enough to say on the drivability.+1 on the trans relearn not being needed.

That all depends on how you plan on driving.............I average about 12mpg driving how I like to (fast starts, 75-80 on the highway, and just playing around with it in general), I also let it run for 5-10 min every morning/after work which isn't helping fuel consumption.

KEMs tunes are sweet, the best is the 345 it shifts better than any other high HP tune including Spartans (I haven't tried Spartans 300) I can't tell alot of difference between KEMs 275,310 & Spartans 275,310 I think they are both the same tunes originally wrote by Mike while he was at Spartan.
