clutch and spartan tuning

Hi guys first time on this forum i have a 2009 ford f350 cc 4x4 with the 6 speed standard transmission, i've had the truck spartan tuned to the 250hp tune for about the last year and love the amount of power it makes, now to my questions I'm hoping to upgrade the tune to maybe a 275 or 300 as the 250 seems to be very sensative to throttle pedal input, what i mean by that is that when driving on rough gravel roads its hard to drive at slow speeds as with every bump I hit the truck seems to buck a little i dont get this when i run the 210 or lower tunes and was just wondering if there are any higher hp tunes that are not so sensitive to pedal input, also with a higher hp tune i'd like to upgrade my clutch i dont tow very many heavy loads and my towing is pretty much always under 10 000 pounds and only three or four times a year ive been looking at the south bend dual disk clutches and would just like to hear some feed back on them, any help would be greatly appreciated. thanks

When I replace my stock clutch I'm going with the South Bend duel 3600. Have you been running the 250 tune with a stock clutch?

That's pretty damn good. If I run the 150hp it will slip the clutch, stepping down on it at 40mph. I just run the 80hp for now till I get a new clutch.

The higher HP tunes are all sensitive. Matt made them that way for the manuals for faster shifts between gears. I've ran the 310 tune in my '08 6 speed, and now in my '10 6 speed. That was an update he did a while back. You'll notice that when you suddenly let off the throttle, the truck falls on its face? That allows the shifter to pop out of gear much faster/smoother.

I'm running the 310 right now with the stock clutch, but I have to baby it to keep it from slipping. I've already got the sintered iron dual disc ready to go in, it's just a matter of getting time to install.

Thanks for the input guys I installed the south bend dual disk yesterday and so far it seems very good, it actually seems a little easier to press down than the stock clutch, I went with the 750hp set up as I cant see myself ever goin beyond this but who knows, Slick Willie how do you like the 310 tune does it smoke like crazy or is it berable I was thinking of maybe upgarding to it at some point in the future.

Easier than stock? That's crazy talk! Both SB clutches I've ran were 3600# dual discs and both were much harder to push than stock. I never tried to shorten the rod to make it softer though. The dual disc I had with buttons held the 250 tune for a long time, but wouldn't hold the 310 tune when I upgraded. The sintered iron would hold the 310 no problem, but I didn't run it for long. I'm about to put it back in, so maybe I'll have more results by the end of this year after I put a bunch of miles on it. And don't forget, that 750 hp rating is at the flywheel, not the wheels.

The 310 is a race tune, so it's jumpy, but it's definitely a performer. It shifts fast, spools up quick, and is night and day different from the 250. It smokes the most out of all the Spartan tunes I have. If you ever get close to Texas, let me know and we'll take a ride.

Thanks Slick I'm aware that the 750hp rating is at the flywheel but I figure with the 350hp stock plus the 250 that the tuner provides im only at about 600hp so even if I went with the 310 tune i would be somewhere around 660 or so so as long as I dont drive it like I stole it or do any tractor pulls I should be all good with a 750hp clutch I"ve done an air intake and a different cold air charge tube but cant see those mods giving me any major gain in hp I also cant see myslef doing any more than that to the truck at the moment so I think for now the clutch should be fine time will tell how good the clutch will hold up and how many miles I will put on it. but if im ever in your area I'd be intrested in seeing how another standard performs as it seems like they are few and far between

I thought you said that sintered iron clutch broke your input shaft?

Him shifting like a maniac is what broke his input shaft.
