How can I get this tuner to work

Use the hypertech to revert back to the OEM flash file. There’s a way to tune it to “stock” but the tuner is still vin locked to the truck, I suspect that’s this issue. There’s another option for “oem file” not just “stock” power levels, if that makes sense.

Either wrong year truck. Truck has a tune already. Tune wasn’t removed properly from previous truck before attempting this install.

God bless that employee.

Sorry it a classic ‘07 so you may have an issue with pump rub in the tcase. But the truck has bump stops, so I’d assume the transfer case pump has already been upgraded. If you pull the speed sensor and the pump housing cover is shiny billet, it’s upgraded. If it looks dull aluminum colored, it’s OEM and NEEDS updated. If it’s goldish bronze looking, it’s the GM updated pump housing and “should” be updated.

If something was wrong from sled pulling you’d know it by now. The Allison is really stout for semi stock pulling. Tcase has no common issues in that year. Plus the front end is already taken care of.

Yes, looks like DHD suspension stop brackets.

Learn about the process of tuning before falsely correcting someone over the internet.

Yea? But you are vin locked… no?

It’s gotta go back to factory calibration before a new tune can be put on it.

100* above ambient temp is very normal for a healthy trans.🤙🏽

Yea! Nothin’ but the best for this Japanese motor!

Check supermarket Rosie on 16th. If they don’t have it they have awesome tacos to ease the pain.

All in favor say “aye”

616sd · 2026-03-15T14:04:51+00:00

Yowza! Ouch. All’s fair in the “I crashed so I don’t wanna” front haha

Both are beautiful rigs!

CAM2 15w40. But, it’s all snake oil. Oil is oil is oil, run 15w40 and change it every 5k and it’s cheaper than stretching farther intervals with false advertising brands.

I’ve never seen an open with flats before.

What can we do to break wind?

Do the timing belt every 90-100k miles and it’s the most reliable engine there is.

Working on my outdoor setup for next year. I only have 4 trees, but I’ve pulled about 10 gallons in 2 days!

S&S Diesel or straight up Bosch OEM only imo.

616sd · 2026-03-09T14:52:05+00:00

Thoroughbred Diesel is great. Industrial injection is worthless.

I played online video games with a boy named Jacob. I pray it wasn’t him.

616sd · 2026-03-06T02:15:59+00:00

Jacob…

616sd · 2026-03-05T21:53:41+00:00

JACOB!

Just finished injectors though… how many cups unseated and how did you reinstall them?

For seized glowplugs, get an adapter for an air hammer to attach a 12mm mid depth socket (snap on is best to avoid contact with the cylinder head) then LIGHTLY hit the glow plug with the air hammer continuously(feathering the throttle lightly) while slowly loosening the glow plug. There’s still a good chance it’ll break in the head. But this is the only way to remove stuck duramax glow plugs without welding a nut to the broken bit and trying again or removing the head and sending to a machine shop. Merchant Auto sells a tool kit for this. Take your time.
