Hi NCHornet, Yes this is my 03 SD. I'm making a steady 25-26 pds of boost when the EGT's rocket up. I'm not sure but I think if I stayed on the pedal the EGT's might even go higher. I don't have a CAT just an MBRP Muffler. The truck is an animal on the extreme setting. Blows "Tons O Smoke" jumps out of the hole hard and builds boost quickly along with the EGT's. I can only stay in it to about 70 mph. When I lift they instantly go down to 800 deg.
At road speed (70 mph) I'm running about 650-700 deg. in the extreme setting. All of the other tunes Stock, Daily, econo, Tow, Heavy tow never go above 1200 deg. no matter how long I stay on the pedal.
As far as the trans goes. I had spoke to a friend of mine who owns a trans shop about pre mod upgrades. He said don't bother the stock 4R100 trans and Torque converter is junk and since I had 77K on it it was just a matter of time. The only way to upgrade is to pull everything and replace the torque converter and a bunch of other internal parts. So he told me to run it till it blows. So, I did and it did. Only lasted 4 days to limp mode. Blown Torque converter. Bent valves in the valve body, etc... Mass carnage. New trans is in and I can tell the difference. It hooks up even harder. Must have been slipping a little before and I didn't notice in stock form.
