    dont take this the wrong way, but that is why i dont deal with cat shops anymore. all they care about is the warrenty back lash and not on how to treat the customer. i know they have their hands tied on the epa bs. i own the engine not cat!

    Well with that being said that makes be think that I should just go with the 6NZ C-15 550hp 1850T rather then the C-16. Everything I read says the stock C-16 is a pig on fuel with out a tuner and other upgrades and that the stock C-15 550hp is not bad on fuel and pulls good...

    They are not like that when it is no warranty- but if it is on warranty- it has to be in original condition, I agree that if it is yours, you can do what you want, but cat gives me my paycheck

    Your rut, it is a pig 3-4mpg for the 600-625s, but it's 6-7 mpg on the 725s, they all u the same fuel #s (fls/fts) and the flash file is what does the difference-different fuel maps for the different hp ranges

    But from what I understand from you is that going to the 725hp will kill any warranty... Right??

    No, if you build it to cat spec with the right in frame platinum kit, pay for the new file (all iron must meet their spec) to get full 4 year unlimited mileage/ hours+ esc and free town g coverage, and the cherry is that it's a true 725! Just make sure ur trans can take it

    When you do the opt's, that's the best time to update/rerate your engine to a higher horse, ex: 475 c15, build it to a 625 and the kit costs the same, just $500 more for the software all warranty approved like I said 4 yr unlm miles/hours, and free esc upgrade which covers towing

    How are the C-15 625hp engines on fuel vs the 550hp

    From what I see (in Alberta) around 5-7, depending on how it's driven, idle time etc for the 550s, 625s are 4-6, which in my eyes is quite decent for the power, I've seen both as low as 2/3 though
     
    NFDDJS Thanks this.

    yes i know your hands are tied on those issues. all i know is the local shops i have dealt with ended up going through an attorney to get satisfaction. it wasnt the mechanics it was cat corp higher up's telling me what i could and couldnt do! they were wrong!
