Question diesel performance

while getting my 2001 ford diesel serviced yesterday the mechanic told me if i put in an aftermarket chip it would improve my performance as well as increase my mpg...does anybody have any feedback?....
banks?
hypermax?
etc.?
thanx...

Yes,

A chip will get you more hp, as far as mileage goes I wouldn't expect a huge gain. Most of us hop the diesel up for more power but when doing so if you get too radical then you will need additional parts to handle the extra hp, guages, exhaust. My 95 has got a Superchips reprogrammer in it which is what I'd recommend for your Super Duty. You can change the settings with it, with a chip you are stuck with whatever program it has.

super duper

actually i am satisified with my 7.3 turbo...but the thought of better mpg is enticing...doesnt the chip also lock the trans converter?..... and improve towing?....and tell me about this super duper reprogramer...havent seen that one...

The reason that your factory chip produces the power that it does, is two-fold.

One, it prevents overtemp and overboost under most circumstances, so drivers don't have to watch gauges. If you chip, make sure you install EGT and boost gauges first, and watch them like a hawk under heavy power application. Even the so-called "towing" chips and programs can easily overtemp the turbo.

Two, it limits the engine power to the rating of the drivetrain components. For example, on the 4R100, that's 1000 ft-lbs on the input shaft. If you multiply the stock 525 ft-lbs times the 1.82 multiplication of the torque converter, you're there. Exceeding the rating doesn't necessarily mean instant failure. It just means that the mean time between failure will be shorter, and the probability of failure will be higher.

That's why Ford can void your engine and drivetrain warranties (but not things like the radio), if you chip or reprogram. Ford is notorious for doing that.

The gear an auto tranny puts you in is dependent on road speed and throttle position. With a chip, you're injecting more fuel (and making more power) at each throttle position for each given speed, so for any given power need at that speed, you're using less throttle. Using less throttle means the tranny is less likely to unlock the torque converter, or downshift. If there's any mileage gain, it is due to that.

The stock 7.3L PSD produces more than enough power to tow a 10,000 lb triple-axle, and the Duramax and new 6.0L PSD produce even more, especially at higher rpm.

We have the Western Diesel chip in our 97 Powerstroke,for the past 32,000 miles.As for torque increases, there's a noticable change between 1,600 to 2,500 rpm. As for improved mpg.,we haven't really seen any increases,in ether city, highway,or towing. If you plan on getting more than a chip for your truck,plan on getting some additional gauges,even just a chip increases operating temps.

I can't take credit for that, Norby. The tranny info is from the selfless contributions of a Ford transmission engineer on the RV and Ford Diesel (www.thedieselstop.com) forums. Some is also from the crybabies who hot-rod their truck and then whine when Ford won't reimburse the dealer for the repair. If you're gonna play, be ready to pay.

diesel performance

I read a news release that the 2004 1/2 Ramcharger diesel will have 600 ft.lbs. at in a usable range (not specified).

I have read somewhere on the internet ( can try to look for it again if interested )
That there is a system that injects porpane in a diesel engine
it suposed to work great and give more than enough extra HP when needed

For porpane injection, try www.bullydog.com.
Good reviews on another site.

Is the truck power train still under warrenty? It will void it.
Want better milage back off the throttle. Re-programming for better milage requires leaning out the mixture. Not good unless you can watch the Exhaust gas temperature(EGT). To high and you damage the engine. More power more fuel. That can drive the the EGT up as well. The computer is maintaining a fine balance. You will be messing with it.

RoadKingMo was accurate in what he said. I run a 7.3L with a DP Tuner chip with 2 extra setting, one is a 60 Tow setting that does change fuel maps but also does a great job of changing the shift points for better towing acceleration but more importantly it hold the torque converter locked much longer providing safe engine breaking in the mountains and less heat into the tranny. I don't hot rod my truck, but the power of custom chip is significant - my MPG unloaded on 80 Economy is about 19.5 mpg at 70 mph - towing I am about at 14 mpg.

If you decide to chip gauges are a MUST have, I'd have them even if I didn't have a chip. The 7.3L is a very capable and well designed motor - it can handle responsible power upgrades easily. That said - you can make some great improvements without a chip too - intake, exhaust and check your up-pipe and intercooler boots to make sure you're not loosing boost.

Finally - don't be confused by issues 6.0 motors have - the torque-flex head bolts and EGR issues are individual to those motors and are exacerbated by heat.

If you're thinking about a chip - call the guys who are doing the programming - most are very knowledgeable and provide intelligent data driven information.

probably not.

this thread is 6+ years old till 2day.

a true zombie thread on fords, bumped to ask about mopar?

cool.

and as i recall norby has an E350 van with 7.3 or did.

these have slightly different plumbing that the F series, although moe's advice was great then and still is now.

cheers
