spartan 310/300 or kem 310??

[venom]

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, kem? Heard good things about both.

thanks

I have the 300 and the 310. I love them both. The 310 has a lot of power but it does shift hard. It doesn't bother me that much but my wife hated it so I switch to the 300 and she likes it a lot better. To me I think there is a difference you can feel between the 300 and the 310. It seems like the 310 has more power but I figured that much. If you get the spartan 300 and 310 you will love both of them. And I was also coming from driving the 250 tune for a while.

I have all of them except the 300. the kem 345 is the best driving tune, not the fastest but the best driver by far.

went with the kem345, great power and shifts smooth.

What kinda economy gains are you guys seeing going from the 250 to the 345? I'm about ready to upgrade myself and looking for more mpg and drive-ability than power.

Thanks, I'm finding myself babying the truck more now that diesel is at $3.00 a gallon and rising it seems. So shouldn't have a problem taking it easy with the higher tunes. At least after I play a little

I got 14mpg on the 345 in town and towed a small trailer some. Just filled up today. Liometer was way off reading 19.5.

I just loaded up my kem 310 tune the other day. I got Mike at KEM to custom make this toon to shift smoother. Its got plenty of power and the shifting is even smoother than the 250 tune. Awesome tune IMO
