Has anybody used custom OS 03190003 on an '03 6.0 liter (fairly stock,no supercharger)?
I followed the Custom OS tutorial using a tune file with valid data and a pretty accurate VE table. After adjusting the various table values as instructed in the tutorial, flashed the tun(OS was 03190003) into my 03 2500HD, I went for a drive. First thing I noticed was that the shifts were much harder than they even are during the stock OS VE tune. Second and probably the most terrifying thing was that the truck shook violently when just cruising down the road. It was 3-4 quick jerks in succession.
And lastly, my STFTs were insanely rich (I've previously posted about this topic). If my tune works great for the stock OS and only mods after custom OS were the basic settings covered in the custom OS tutorial, what could be causing these problems?
I checked P0101, P0102, P0103 in the 2 transmission related tables and they're disabled. I tried a tune with stock torque management, trans pressure, torque reduction and shift times and still had the shaking and harsh shifts.
