I have a 2003 crew cab dually running juice/attitude on level 2 and low boost on level 1 that I bought in January. It was great. I could stand on it and get up and moving. I could easily pull either one of my trailers with no problems with EGT's.

2 weeks ago I hit a deer and I just got the truck back last Thursday. Now under moderate exceleration, the truck blows alot of black smoke and the egt's rise to an unsafe level before I get up to highway speed. Could the dealer have done something? I have not towed anything since I got it back and I'm worried that I will have even a bigger problem when I hook up to my trailer. Any advice or help is greatly appreciated.

What did the dealer do while it was there?

They replaced the radiator, transmission cooler, AC compressor, and every front exterior part such as the lights, grill,bumper, etc.

bad intercooler maybe?
