I am new to this forum and I joined mainly to see if I could get some feedback or info on an 8.3L ISC cummins I have in a 2010 Freightliner M2 I recently purchased. It is a 330hp and I am going to delete the egr and dpf filter, it has no def, and I was wondering if anyone had any first hand knowledge or info on how those engines handle a higher HP tune. My experience has pretty much been confined to the duramax engines. Currently I just use the truck to pull a LQ horse trailer which weighs a little over 15k empty and between 20 to 23k loaded. The truck has no issues but it does pull it similar to my 3/4 ton lb7 does when I pull a heavy trailer with it. (Meaning slow acceleration at highway speeds when you may want to pass someone, drops speed significantly on hills but will move right along on the flats as long as there is no head wind.) It has the Allison 3000HS 4th gen transmission on it as well. What I am wondering is, would an increase up to say 400hp be to hot for the cummins or the allison? If it were a duramax I would have no concern with it or the allison transmissions with a 70hp increase but I do not want to make any assumptions on something I have no real experience with. The other question I have is, will doing just an egr and dpf delete be enough to "wake" it up for better mileage, acceleration and such? I know that it will to some degree improve all that but wonder if that alone would be enough to get the response out of it I would like. I would just like to get it to pull my trailer a little more like my 3500hd LMM duramax that has a 50hp tune with egr/dpf delete and will pretty much walk away from anything pulling that same trailer up hill or down. The only draw back with the duramax is that I really have to pay attention to the heat in the summer time, not so much in the winter, where as the freightliner I can set the cruise and forget about it.
Anyway if anyone has any food for thought, suggestions or advise I would appreciate it.

Thanks for the reply and the info. I did give a cummins tech my engine serial number and asked if that particular motor could be turned up and he replied that 330hp was as much as it could go. I have a guy lined up to come over and do my delete later this month. One other question I have is, if I just do the delete (I plan on just plating off the egr cooler and leaving it on and installing a regular muffler for the DP filter) do I need to worry about installing a pyrometer or EGT sensor or are these engines pretty safe to run by the oil and water temp?

Hi there,
I’m thinking about buying a Freighliner M2 106 with 8.3 Cummins automatic.
I was wondering if you went through with the delete and the tunes and how is your truck currently running?
Are you happy with the truck so far with the modifications?
You could reply by text 7138150809 if you like. I’m just curious to know. I’m going to use this truck for hotshot and would you recommend this truck for this type of work.
Did you get increased fuel mileage and increased horsepower?
