I am getting ready to order my programmer soon and I'm planning on going with the Pheonix but i was wondering about fuel pressure with the 140 HP setting. I am in Iraq right now and so far I've ordered a MBRP 4" turbo back exhaust and a 6637 filter. I wanted to order my tunes so that I could put it all on in August while I'm home on leave. I'm just wondering if i put the 140HP setting on there am I going to have to do something for fuel pressure or oil pressure to compensate for the tunes or will it all be ok? I have an '01 f250 ps 4x4 with 6 spd. manual tranny.

You'll be fine to run the higher horsepower tunes with your stock setup. You may very well encounter some low injection control pressure though. Although this will not harm the truck, it does leave some performance on the table. Fuel wise, you won't be making enough power to even worry about the supply side of the fuel system.

Ok that is what I thought But i figured i would ask someone with more experience than me with this engine. Is there any way to get higher oil pressure without going with a dual HPOP setup? The reason I ask is because I am working with a limited budget here, but I want to get all the potential gains the tunes have to offer. I don't want to end up with half-*** performance because I can't afford to do it right.

There are many HPOP options nowadays.

Diesel site sells a upgraded pump called the Adrenalin, and seems to be having good results. They also make an the Overdrive unit which basically bolts to the front of the HPOP and turns it tad bit faster.

There are Stealth pumps available from Stecher Performance, these pumps come in a few different flavors from mild to wild and can be upgraded in the future if you needs change. They are VERY nice pieces but come at a cost.

Other that changing HPOP's you can switch to a Hybrid injector which uses less oil than the stock split shot will. Hybrid also come in many different flavors, and you will see a sizable increase in HP's. You can run these injectors with a stock HPOP that is in good condition.


I think what ever you choose the price will be roughly the same.....IIRC.

Ok well that helps me understand a little more about it thanks for the info. I should coming home sometime in August so I will probably be ordering my tunes sometime in June. That give me time to get my gauges ordered and shipped to the house by then also. Thanks for the help!

One other thing, whenever I do end up being able to afford a good hpop setup, would installing it on an engine that is not heavily modded cause any damage? I don't want to go too far with it and realize that I'm pushing more oil pressure than the rest of the engine can handle

You can run the most insane high pressure oil setup you can afford (even with stock injectors) without hurting the engine. Tuning the injection control pressure regulator would be crazy, but it could be done.

I ran my Dual Stealth HPOP's with stock engine and injectors will no issues. The only thing that took time was getting the ICP Duty Cycle dialed in. It would spike pretty high sometimes. This was with Elite's tuning, but I am sure everyone has it pretty much figured now.

so to take "full advantage" of the 140hp setting.. could you run an adrenaline or a modded 17 hpop with stock injectors? also would you require additional tuning to compensate for the new hpop?

Bill told me that the Adrenaline was a drop in mod with no need for new tuning.
