Honestly the two main reasons I bought a tuner for my truck are: 1st is to help lower EGT's while towing heavy loads. One common problem with Duramax's is they make really high exhaust temps when pulling hard. There were also head gasket failures in earlier models, I wanted to try and lower the temps to prevent damage to heads and pistons. The 2nd is to take advantage of the exhaust brake function that the tuner provides for the truck. The turbo is capable of doing this from the factory but the engineers did not incorporate it in the stock programming until later models. Tuners and delete kits can honestly make a good truck a great truck, with all the emission and epa regulations it makes it hard to take full advantage of what one of these trucks can really do. That goes for all of the big three GM Ford and Dodge. On the other hand you can get really crazy with these aftermarket programmers and other parts and now pickup truck manufactures are really cracking down on any altering of these engines during the warranty period. Its just like anything there are people out there that take it to the extreme and have a lot of money to spend to blow black smoke and melt aluminum parts.
