    That makes sense. So a lot of that was solved after the change. Did the 1.45 housing make it spool a lot slower or fall off on top? We used to be able to build speed by just mashing the throttle, if we wanted, without shifting down on this long hill here locally. Now it just stays steadily at 70 or whatever speed when we start the bottom of that hill on the hwy. Given the bottom and middle power feels a whole lot better pulling though. That may be because we need a hotter tune or maybe a bigger housing. What were the primary differences you noticed with the housing change?

    Spool wasn't a whole lot slower with the 1.45. It will pull better over all and especially on the top end . The 1.32 felt to restricted.

    Yes.

    Pros and cons to everything.

    If your staying with600- 700 rwhp just go with 1.45.

    Who do you recommend on the tuning? We were thinking about letting DCS do it.

    Not a bad choice. That's who I was using on my 14L I had. Fernando knows his stuff.

    Leon is good too. I can pm you his contact number if you like

    @swaan Would you recommend getting a 14L 60 series for heavy haul 160,000lbs gross?

    Looking at a 18spd with 4.11 rears

    Would I be able to reach about 600HP with a stock motor & turbo?

    What was required to get 625HP? Who tuned the truck and how long did it last or is it still going strong?

    I bought it with unknown mileage but it was a old beat truck. A guy named Leroy who used to work for PP tuned it, all I did was put a 171702 on it.

    625 was pushing that turbo for sure but I liked the spool up better than the 177287.

    Sold the truck after 3 years to a guy who hauls garbage from Vancouver through the mountains, still going strong.
