I've been running the hot damn tunes on the mini switching back and forth from wild to hot...right foot can be heavy at times just wondering how the headstuds and and stock tranny hold up with the 345:thumb::ford:

If you just romp everyday all day then I would say your transmission and head gasket would blow but ive ran the race tune with stock studs and stock tranny but if you drive it right then every once in awhile get on it. You'd be fine. Just my 2 cents tho

There have been lots of people daily drive the 345. Its a good tune. I love mine. I dont use it that often anymore though because I got tired of switching in and out of it to tow. Your tranny will hold up if you dont romp on it all day, but it will cause the tranny to get weaker quicker than lower tunes.

I ran it on stock Tranny and studs. Hate the tune. Wasted 250 bucks on it and Mike wont get back in touch with me which really pisses me off. Got a rough 2-3 shift and smokes like a freight train. My H&S hd300 doesn't smoke near as much and has loads more **** and get. Plus perfect shifts.

Really I've heard it has closer to spartan power with out the rough shifting and less smoke than the hd and spartan tunes...sounds like I will be sticking with the hot damn tunes for now oh well

I had the KEM 250 on a SCT and it was absolutely horrible. It could never find 3rd gear. Made about 51 lbs of boost. Would rev up to 2100 rpm on its own while shifting from park to reverse and from drive to reverse. I hated it. I love the h&s tunes.

i have the 345 tune. the shifts are firm especially the 2 to 3 shift. smoke is controlable, but i dont have the hd 300 tune to compare with. i cant get my hd tunes updated i want to try them to compare the two

I read a thread on here a while back that said the kem345 wasn't really a 345 hp tune. There numbers were misleading. So everyone always thinks that the 345 tune is that big dawg tune but its really not.

I get decent mileage as well 16.5 running 80 and 18 running 70. But the shifting is unreal. Its harsh

Whats the differences between the 345 and 310 tunes. I can only squeeze out 500-515 miles with the 345 file.
