Spartan 300/310 vs kem 300?

Been running the sp 250 now for a couple years. It's a great tune but wanna step it up a bit. Looking to get into a 300 tune for everyday driving with smooth shifts, no cold weather issues and better mpg's is always a +. anyone with any experience with both sp or kem? Heard good things about both.

I recommend giving our 300 tune a try. I have been receiving a lot of great feedback from people who have updated and tried that tune.

I think due to the fueling on the higher tunes you're going to have hard starts and cold weather issues. I may be wrong, but I always run the 210 over winter b/c of rough starts with the bigger tunes

2008 F250 CC SB - It all wont fit in the sig so why bother?

I ended up purchasing the kem 345 tune. Haven't clocked many miles yet but the power is good and the shifts r smooth, so far so good.
