Truck setup 2014 RAM 2500 6.7L with Bd diesel second GEN swap.

I am running a 364.5/80 turbo, stock, fuel injectors stock, CP3 pump, entirely deleted, full turbo back exhaust and BD diesel exhaust brake, RaceME Tuner, and tuned by DRD.

About six months ago, I put in the turbo kit for this truck and had it tuned.

The only thing that didn’t work was the exhaust brake.

It felt like it had a ton of power and ran pretty well.

About a month ago, I had my windshield replaced during the replacement.

The truck got wet because when they removed the windshield, it rained inside my truck.

The tuner screen went crazy.

After that, it says no SD card.

So, I feel like the truck has completely lost power since the tuner was damaged.

I’m working on getting a replacement at this time.

I thought my last setting would have been saved in the ECU.

The truck would not make more than 10 ps; I can’t tow my trailer because the EGT gets too high.

Could the tuner be fried to cause all this trouble, or am I looking at something else?

I ran the truck and checked for leaks around the turbo, but I could not find anything obvious.

The only thing I did find was an exhaust leak after the turbo.

I fixed it but I still do not make more than 10 psi at wide-open throttle.

The truck seems to roll smoke when I’m on the highway, adjusting my speed by 5 mph.

Thanks for your help in advance
