Rmartin-97 · Jan 5, 2012

What's your mods and how many miles you got? Also have you pulled or drag raced?

Mines has 40000 miles been tuned 10000 miles been drag raced and pulled twice still as good as new for now. I have Kem 345 cai,cac pipe and four in exaust.

80k miles on truck - tuned for 15k on xrace/intake/exaust/cac - 20+ drag runs and allot of daily abuse along with a few hauls over 10kpounds - hates life but still is holding fine LOL ...trans is my next purchase.

My buddy has a 2010 with 49k on it. Its been tuned since 43k and all he's ran it on is extreme race. Its seen extreme street twice two different days, once because he was towing and another because he wanted to try and leave it there to be easy on the truck but it didn't have enough power to keep him happy. LOL the truck is also on 35's with 3:55 gears with a fuel tank/ tool box combo. It weighs right at 10k pounds most of the time and the tranny has not missed a beat and its been ran pretty good. Some days are worse than others. LOL

Mines stocker is toasted...
The tranny went at approx 36000km, then I broke the input shaft at approx 68000km, now it's been good with a suncoast and I have 140000km

semperfidooordie · Jan 5, 2012

Truck has 110k on it...been tuned since shortly after I bought it...so about 6k and trans is holding up fine...run it mostly on the Hot Damn and occasionally on the Wild tune...can't complain for a CCDRW 4x4 with 4.30s and stock tires lol...bought to bump up to 35s here soon

Jeff@Spartan · Jan 6, 2012

I went to a SunCoast at 82,000 miles. Truck had been tuned with Spartan 275 and 310 tunes daily for 48,000 miles. Lots of tune testing for Matt, several track passes, and 2 hooks to a sled. Testing for the 350 tune sent my trans south, but it was still drivable when we swapped. Torque converter was slipping pretty bad on big tunes and I had a pretty bad 2-3 shift flare. Fluid wasn't burnt though and it got me from Atlanta to Hendersonville, NC to do the swap, running about 85 MPH the whole way no problem. LOL

CamTom12 · Jan 6, 2012

Sitting at 67k, tuned for 25k. 3,800 of which towed 18.5k across the country from AL to AK. My trans has always had a 2-3 flare. In the cold it actually thunks. It's no worse now than when I tuned. I think the trans was hurt before I bought it at 32k.

OBS F350 · Jan 6, 2012

144xxx miles, tuned for 15k miles, only 210 tune, I'm relatively easy on it, but I've done plenty of large burnouts/drifts/cookies on pavement, doesn't seem to be damaged at all. We will see when I go to the 345 tune

powersmokin64 · Jan 6, 2012

45k 16k tuned and it hasn't exactly been babied, holding up just fine.

Radioflyer · Jan 9, 2012

75k on mine, bought it with 28k, did a DPF and CAT delete in it, afe stage 2, and the SCT off road tunes at around 29k. Made 20+ trips down the track, towing 3+ sleds on a open and enclosed sled trailers, full summer hauling a 22ft wake boarding boat, and a few tow's with full sized skid steers and smaller backhoes. Never took it off the extreme tune on the SCT. Switched to the H&S xrt with hot damn tuning, and the trans seems to be alot happier. So far have made a couple trip's hauling the sleds. No troubles.

pog · Jan 9, 2012

just over 110k. tc showes 90+ tc slip when its locked and floored. and my trucks not even putting out full power (failing hpfp) only 20k frp at wot and tc locked.

Cppr Busa · Jan 9, 2012

153k, 6k tuned with 210, 345 and most time in the 275 kem tunes with no issues at all! I am very impressed with the whole setup! No sled or drag racing though.

Big Angry Hillbilly · Jan 10, 2012

140k km, roughly 90k miles. Tuned since 500mi. Never missed a beat.

Big hp tune in it right now.

David S. · Jan 10, 2012

mine went out around 144xxx miles. Was tuned since 11k brand new pretty much always ran 210 daily. Never felt the need to switch it to a higher tune. Went with a suncoast rebuild after my stocker gave out. And it went through some abuse as well

Dweber · Jan 10, 2012

Has 61000 miles. Tuned for 10000 usually on Spartan 275 tune or else tow tune when hauling pulling truck. Been down strip round 10 Times. Sitting now waiting on new heads and had cracked piston. Still love the truck though

I think he's asking what your setup is: tuner / intake / exhaust, etc.

powerstrokin15 · Jan 10, 2012

28k miles, been tuned since 10k. KEM 345 almost the whole time-even when towing. holding up great. 40-50rpm TC slip at WOT trying to see how much it slips.. and i drive it pretty hard..
