Anyone else got a powerstroke?
I want to change the down pipe off of the turbo.
Maybe one of those plug in computer programs also.

Thanks Tim
I just installed a K/N filter.
The down pipe off of the turbo is suppose to be holding back about 10-15 hp. and 20 ft.lbs. of torque. That's according to the local turbo expert. Of course he want's to sell me the down pipe.
Can you really tell a difference with the plug in tuner?
Mines a 97 2wd. extended cab long bed. Auto also.

word of advice guys,watch out for those k/n filters,esp the replacement filters,alot of these filters don't fit the air box properly,causing unfiltered air to enter the engine.the old k/n filterscan cave in on the ends,these dont have a screen,the new k/n has a screen that fits in a groove/lip on top of the filter,which wont let it cave in,also fits the box alot better,chips/programers,all they do is add more fuel and have a different timing/dwell,(inj on time)add more fuel,make more boost,make more hspwr/torque,all that with stock exhaust,bad....!!anything over a 50hp increase should have some exhaust,also depends on how u drive also,dont forget the trans,all that hp/torque will play hell with that stockshifting trans,shift kit it,transgo makes a kick ass shift kit,last but not least maint,maint,maintenance,keep those fluids and filters changed.

After changing a few transmissions at work I can see where the pipe would cost some performance. The pipe is as flat as hell coming from the turbo down to the first converter. There’s no room between the trans and the firewall, floorboards, so a performance pipe might be a bitch to install, the stock pipe would be hard to remove without un-bolting some mounts, it’s real tight in there.
I got the pleasure of keeping 9 trucks running all 7.3 Power Strokes except for the new one witch is a 6.0.


Let me know if you have any drivability problems cause I’ve seen a lot of them.

Cam sensors
High-pressure oil pumps
Injectors
Injector seals. That was a good one; truck went through 12 quarts of oil in 25 miles, no leaks and no smoke. I went crazy trying to find out where it was going. After pulling most of my hair out I pulled the fuel filter cap off and found the oil. The o-rings on some of the injectors were bad and the high-pressure oil that fires the injectors was bleeding into the fuel side of the system. The oil was in the fuel tank!!!
Glow plug relays
Head light switches like you read about.
Water pumps

I have run my Superchips Supertuner 60 hp/115 tq for over a year and a half. I have had zero probs. The engine makes alot more low end power and better power overall. The trans shifts better also account slight increrase in line pressure.

When I get home from work tomorrow I will check my K&N.

Ive been told the factory muffler is very restrictive by other PSD owners. Im thinking of removing all together.If it is to loud then I will look for a high flow muffler.

thanx for the link Tbolt

Im trying to find what the stock exhaust pipe size is exactly. I know the down pipe on the year I have is 3 inch but I cant recall the exhaust size after the down pipe. Is it 3 or 3.5? anyone?

I think the downpipe that Banks makes is two piece. Suppose to be easier to install.
The new K/N filter I installed fits like a glove in the stock airbox.
Other than the heater/blower motor going out two weeks ago, it's just been oil and filters since new. Of course I only have 47K on mine.

393Clevor pretty much cinched it for me. I can't afford to buy a low mileage diesel, and don't wanna get stuck with the possible astronomical repair bills that can come with a higher mileage unit. Unless I stumble across a deal on a diesel that I can't refuse I am sticking with gas. I don't tow on a regular basis, I don't drive a truck over 15,000 miles a year, so I just don't think it is going to make sense economically. I'd love to have a diesel, but I just can't justify it.

The plug in tuner of chip is the best bang for your buck. It makes a huge difference in performance. The chip not only increases HP and torque, mileage increase are common (but not if your in the throttle). It also gets rid of the annoying throttle delay. The downpipe is a restrictive piece as well, although if you want a big performance gain for your money, go with a chip and you won't be sorry. I have a '99 powerstroke myself I tow 13,000 pound trailer with frequently (40k plus a year), and I went from 10 to 12.5 MPG loaded-in similar driving conditions. Take this as you may, but I also sell many different diesel performance products and own a chassis dyno including flash tuners and 'chips' which you can switch on the fly. Don't mean to be a salesman, but if you really want good tech info, contact me @ [email protected] Have fun

watch the 4" down pipe with a stock turbo exhaust housing.it will have some severe turbo lag compared to a 3
31/2 down pipe,a stock down pipe on a 99-03 7.3l is about 2 7/8 at the turbo and 3" after the crossmember,the 4" down pipe will give you about 200-250 deg cooler egt than the
3- 3-1/2,but the smaller down pipe will give a little bit better throttle responce,I like the 4" banks kit with the exhaust housing,compressor wheel,and big head actuator.great throttle response,low egt and good clean boost about 25-27 psi at wot going up hill pulling a 15k trailer with 950 egt at the turbo.

Superchip claims that you can go back to original factory setting in no time. What I want to know is if these computer enhancers are tracable. Some of us have chosen to opt for the extended warrantys, and want more performance. But don't want to take thier rigs back to the dealer only to find out that the dealer found out that you had messed with the computer, therefore you voided your warranty instantly. Has anyone ever come across this situation?

some turners will leave a P0603 kam code(keep alive memory)or a waste gate code,or a over boost condition,a perf chip or programer can't void the entire veh warranty,say you are running down the road up and down hills pulling 15k.80hp chip or programer,trans takes a dump,torque converter is black and blue from excesive heat,and clutches are burnt aswell,or turbo blows its guts out,you are pretty much sol.would a stock veh normaly do that?No! since you added 80 hp you have added axtra heat to turbo and trans,thats why you need big exhaust and shift kits,to get the heat ou of the turbo and have the firm shifts,its just like hottodding your 5.0L you have heads cam and intake and stock shifting trans?...... now same scenario but water pump fails,oryou get a severe oil leak.high press pump orings,that chip is not going to cause those items to fail.now....trans leak a tail shaft housing,should be covered,torque converter hub seal leaking,defective seal should be covered,same seal leak caused by black and blue converter with 80hp chip you'll probobly pay for it.guns dont kill,people do,chips-tuners dont kill,poeple do.ford builds safty margins in there powertrains,speed gov,engine rpm cut outs,etc,you chip it,you you raised the perf bar,and took out that safety margine,you just have to drive smart,watch your guages,esp exhaust gas temp,and trans temp.

I just installed the 3 in. down pipe, Edge evolution programer, and egt/boost gauges.

What a differance the controler makes!

At a steady 60mph, the egt temp is 500 degrees and the boost shows 2 lbs.

It makes a "ton" more torque.
