More HP, same MPG? Upgrades/Mods?
I want to make some mods and upgrades without hurting my fuel economy or jeopardizing the integrity of the engine. Yes I know that anything really can jeopardize the integrity of the truck but within reason. It has a 4" turbo back exhaust, I was thinking of going with a 6 position chip, an upgraded turbo, I know nothing about them but everyone is talking about a 38r, a S&M intake, and maybe changing out the inter cooler. If I could make 400-450 hp that would be great, 500 would be awesome but I think thats a little much to ask. Whats your opinion, mods, upgrades, hp?

Set a horsepower goal that fits with how you use the truck, then set a budget...
Once you have those two figured out... You need to start researching injectors...https://www.dieselbombers.com/99-03-...tml#post528193 38r would be a good upgrade to the stock turbo... Chip with some custom tunes... You will need to beef up the transmission... You might want to start looking at studs, springs and pushrods. |

2001 and newer PSD's have PMR's, which are powdered metal rods, L99 and 2000's have Forged Rods...
The PMR motors are good to about 400 HP, while the Forged rod motors will handle up to about 500 HP. Beyond that both motors need head studs, springs and pushrods replaced. Your good having a 2000, you can handle up to 500 hp. I am in the same process in that I am modding my truck, I chose the 38r and I love it, then I went with the TS 6 Position chip with Tyrant custom tunes...I am very happy so far. Next I am going to install the 238cc/100% injectors, then go with a regulated return fuel and fuel bowl delete system. I will address any oil issues after that, IF I have any at all or my stock HPOP let's go. I tow a 35 ft Toyhauler that when loaded is about 12,000 lbs, with the mods I am shooting for I should be still reliable and have manageable EGT's...I am shooting for 400-425 HP, I might be touch over when its said and done.:c: |

When I am towing I'm hoping to maintain 11-13 mpg, running empty I am averaging about 17.5 -19 mpg.
Theoretically, if you the mods help the truck get along down the road more efficiently it will get better mileage...as long as you keep your foot out of it. My biggest concern are the EGT's, I have to climb steep passes pulling my trailer, so I am concerned to not build a really hot running motor, empty will be fine... |

Sounds like a little gypsying...should be a lot of fun. Do you work on a Drilling Rig?
What kind of trailer are you looking to get? I have had my eye on a 37' Raptor, but it's just way to pricey for me. Will be sticking with what I got for awhile.:tu: |

My goal is 400+, budget, not really a concern, it has a beefed up tranny already, I have been hearing these stock 7.3's can handle 400 with the studs, springs and pushrods they have, is that wrong?
In fact, If budget is not really a concern, I would do it even at the 400 hp level... They are added insurance... |
