I recently bought a 2001 F350 7.3ltr, i didn't know at the time but it has some mods, I have a few newbie questions. so far ive discovered a banks wastegate, cold air intake, and it has a chip (not sure what kind though). Found out about the chip during a tech scan to solve a problem that was beyond me. i have a feeling that more has been done because this truck is fast, very fast, but im worried about the longevity of my truck. It also has turbo back 4" exhaust with tip, boost & pyro gauge and almost certain something's been done with the turbo, cause when you put your foot in it, it'll ping the 30psi gauge. My question is how can I keep or gain more power without sacrificing the longevity of my truck. Keep in mind its an automatic, which I'm willing to improve on too if needed. Any help or advice would be appreciated greatly.

 

A stock truck with a tuner (or flashed PCM) and air mods can hold 30 PSI:




This is what happens when you step it up a notch (same truck, bigger mods).



Got pictures under the hood? There's no **** or controller on the dash for changing the program? Do you have pictures of the truck? Private party or dealer?

 

Welcome to FTE... Were here to help.

The first thing I would recommend is you take some pictures of the truck and post them up here using photobucket or equivalent. If there is something different from stock the watchful eyes here I promise will catch it.

 

Thanks guys will get them up in a day or so, this is my first diesel and I want to do it right. An equal balance of power and reliability.

 

You may have a Banks PowerPack, in which case you may already "have an equal balance of power and reliability." Having spent a little bit of time with Gale, I can say from personal observation that reliability, durability, emissions compliance, and no smoke are extremely important aspects to his product philosophy, and I've watched him instill and insist upon that philosophy into his employees and engineers.

You've already discovered the Big Head and 4" exhaust. To find the other clues, get a good strong flashlight take a look at the rusty side of the turbo (exhaust turbine, passenger side) and see if the word "BANKS" is cast into the turbine housing. While you're there, take a look at the big fat pipe (downpipe) that turns down from the turbine toward the exhaust. Does it have a sensor tapped into it?

More clues: follow the intercooler tube from the compressor side of the turbo (inlet on the driver's side) to the intercooler upfront. Shine the flashlight down in there. Are the header tanks of the intercooler aluminum or plastic? If smoothly shaped and aluminum, you have a Banks Intercooler. Banks pitched the stock intercooler in favor of one that has larger header tanks with smoother flowing transitions into the heat exchanger.

More clues: Look at the muffler. Is it cylindrical or ovalized? If cylindrical, does it say BANKS on it? If so, then you have the Banks Dynaflow exhaust system (consistent with your reports of a 4 incher). What is not visible about this muffler is the semi-torus shaped inlet that applies a venturi effect to the entering exhaust gasses by partially (and smoothly, due to inner diameter characteristics of the torus ring) constricting the gas flow which then can immediately expand into the muffler chamber, accelerating the flow and thus reducing the net restriction.

More clues: Look under the dashboard, by the emergency brake pedal. There will be a rectangular box that juts toward you from the firewall, by the driver's side kickpanel. This is the PCM (engine computer). The engine computer is held in place by a plastic housing that often needs to be cut in order to fit a chip into an otherwise unused testing port on the PCM (called the J3 port). If you have a Banks chip circa 2001, then you will see the label face of a small Banks Ottomind module plugged into the the leeward end of the PCM.

Your boost and pyro gauges are also clues. What do the gauge faces say? Banks brands just about every product he sells, so even though the gauges may have been made by Isspro, they will say Banks Dynafact on the faces.

 

Geez.... Don't give away all our secrets. Where's the fun in that?

 

Thanks a load for all the help guys, I'll get back to you all with my findings.
