2008 Ford F250 - Build A Better Super Duty

During the past six months, we've partnered with Airaid to test the most popular upgrades that readers make to their Super Duty trucks. Our goal was to see how the new '08 F-250 would respond to an air intake, an exhaust, a programmer, a lift kit, and tires and wheels. Working in stages, we began by upgrading the exhaust with a MagnaFlow system that replaced the stock hardware from behind the diesel particulate filter. Then we added Airaid's latest intake system for the 6.4L Power Stroke to ensure that the two upgrades would work in harmony.
Evidently, some exhaust-system and air-intake combinations can trigger a check-engine light when the backpressure sensor gets out of its operating range. Fortunately, we didn't have any issues with the Airaid and MagnaFlow combination.
For our second buildup stage, we installed a 4-inch Rancho suspension lift and 35-inch Nitto Dune Grappler tires mounted on the factory Ford wheels. The new ride height improved ground clearance, and the Dune Grappler tires were some of the smoothest and quietest 35-inchers we've tested. To see how big a tire we could fit on the Super Duty with the Rancho lift, we swapped on a set of BFGoodrich's redesigned 37-inch Mud-Terrain tires.
This month, we'll bring you the third and final stage of the buildup. Over the next 15 pages, we'll show you the latest upgrades for the '08 Super Duty and even throw in a roof-rack install on an '02 F-350 just for good measure. If there's something we left out that you'd like us to add in the future, drop us a line at our new e-mail address, dieselpower@sourceinterlink.com, and we'll bring it to you in a future issue.

Very nice truck! I know a lot of 08 owners will enjoy this because they want to do the same things to their trucks, but not if it will cause a lot of problems!

Cause a lot of problems? More than they already have? My buddy owns a landscaping and excavation business. He has a F350 SRW CC that he ended up making his personal vehicle because he can no longer tow with it (the 8in lift doesn't help). The power went way down with the 36" tires, and he's had quite a few problems in just the 6 months he's had it. Now all of his company trucks are either Chevy's or Dodges, and while the Chevy's have a few more suspension issues (CV boots and joints) and the Dodges have needed computer updates and TPMS malfunctions, they have been much more reliable than the Fords. Just seems like they should be focusing more on longevity than pimping it out.

MotorOilMcCall · #7 11-20-2008, 08:48 AM

I have 1,106 miles, and no problems, running sweet & alot faster than my 7.3.

Consider yourself one of the lucky few...

If you see the DVD that FORD is giving out on the SUPER-DUTY 6.4 PSD, it's suppose to be the best truck ever made. All the parts are bigger & stronger than the chevy & dodge, The water pump is twice as large as the other 2 trucks.

MotorOilMcCall · #11 11-21-2008, 12:12 PM

LOL... I'm sure it is, they need all that flow to cool the block that has a poorly engineered water jacket. You know the 6.4L was originally designed to be a 6-Cyl right? No joke.

I've got an 6.0 with 100 000miles on it now with a 6" lift 37's.....well you can see in my signature but the only problems I've ever had are the abs dont work cause the big tires throw the speedo out and the egr goes but besides that no problems ... o and I broke a u joint once but I was being dumb.

I keep hearing from everyone that the 6.0 is crap but even from owners but I dont personally know anyone that has ever had a real issue with any part of the truck

You need to get a tuner that will adjust your speedometer for the 37 inch tires !!!

atrd86 · #15 11-22-2008, 04:08 PM

The PMT does and it took for a bit but than the speedo went nuts and now is just back to what it was before. Apparently the 05-07 have a glich and if it doesnt take permanently there is something a matter with my truck and it cant be fixed.

When I had the tires put on the dealership said they were going to adjust the speedo too and I noticed it wasnt done, when I talked to the manager he said he made sure they did it..... so I guess I have to live with it

but I dont like abs anyway and I have the speedo on the PMT anyway. So mabey it will help me get out of a ticket if I have to
