Does anybody else have this issue??

Ok so the family business bought a fully loaded cab and chassis F-550.

It SUCKS!! It has ZERO balls and barely pulls 25k lbs at like 70... all while getting 4.2 MPGS!!!!

Does anybody else have this problem? I know the cab and chassis trucks are detuned in comparrison to the regular 6.7's and that they only have the single turbo vs the dual one... but holy crap! Is this normal?

Also, now that my dad actually drove it he realized how much it sucks and has asked me to figure out if its the norm. And if so would doing the full DPF/Urea delete and some tuning actually help anything?

He really wanted to keep it stock for warranty reasons but if it's gonna be like this he'd rather open it up.

Thanks for any help!!

The people I know that have had C&C trucks said they sucked and had no power.

Well that sucks...

Does anybody have a C&C truck with deletes and tuning? Maybe some input on how much, if any that it helped?

IDK that I would delete one the way C&C eat turbos

70 veiws and 3 replies???

Bump lol

I agree with what I've seen for the c&c dropping valves and turbos I wouldn't wanna chance the warranty.

Why not just run dpf on tuning?

I would do that. I'm just curious about how much it would help before I spend the money...

We have a c&c truck at work. Same exact issues no power and horrible mileage.

Ya it really sucks!! You buy a 60k dollar truck that runs like an 85 chevy and gets 4 mpg...

I test drove a c&c yesterday and I have to agree, they are dogs. That thing wouldn't get out of its own way.
Horrible horrible acceleration, I have no idea why they felt the need to detune the truck 100hp but it shows.
Took a F350 dually for a drive next and all was well. Gotta have one. SRW of course.

Are all c&c trucks like this or just 450 and 550? The reason I ask is my uncle just ordered a 350 c&c

Low end power will be better than normal trucks, but top end won't be the same as normal trucks though (per Mike)

I was told all cab and chassis are detuned and having low gears are not helping mpg. I think if you get a f450 with body it is not detuned. This is how I bought my new F350 utility just had them take the body of and got $1500 for it. Deleted it and runs great.

Seems like I read someone put the 250/350 turbo on a CC truck. I can't remember where I saw the thread, but I'm pretty sure it's been done.

Personally I think throttle response is the truck's real issue. The power doesn't come on for a long time, then it hits hard. For pulling out in busy traffic this is rough, especially on the rear tires.

What little I've towed with it hasn't been noticed back there. I can feel it when braking, but there's so much power on tap that pulling is no issue.

I have a f550 and its a dog pulling a trailer. I have pulled the same trailer loaded the same with a f250 and it pulled it better.

I know its apples to oranges, but my buddy had a c&c cc f450 4x4 7.3 truck, and it ran about like a stock 7.3 truck pulling 7k lbs. Even when empty..and got horrible mileage...you woukd think that gearing could overcome the lack of power, but I guess its a cab and chassis issue.

We just received our 2012 f450 with a normal pick up body and it tows great gets 12.5 mpg towing 20 k and gets 15.3 not towing. Interstate driving is not great with the 4.33 gears though this is with 1500 miles on the truck so far.

Hmm, my 2012 F450 DRW empty still only gets about 13mpg, havent towed anything heavy yet. Not sure I can afford the fuel.
