Modifying a diesel pickup--what\'s allowed

Fellow Posters:

I have a 2002 F-250 7.3 L Power Stroke diesel with which I am very happy. A little over a year ago, I installed a Banks Power Pack system on my truck and it has worked great. So great, in fact, I would strongly consider installing one on any new truck I would purchase. My truck has 51,000 miles on it and I am not in the active shopping market for a new diesel pickup just yet. Generally I trade at 60,000-70,000 miles or 80,000 if I like what I own a lot. I am not particularly brand loyal, I have just always owned Fords. They have given me good service and I like them. There are some features unique to the other brands that would make me consider them as options if I were to buy; and as it turns out, it may be financially beneficial timing to trade later this spring for me, if I am to do it. Does anyone have experience with any of the "big three" and their new policies on aftermarket mods like the Power Pack on a new truck? I know Ford has really clamped down on this since the purchase of my truck, especially when the 6.0L was initially released and service issues arose. My friend has an F350 truck with a 6.0L that Ford refused to warranty because he had an aftermarket exhaust, even though his warranty issue was unrelated (a fuel delivery problem). I have read one report of Chevrolet not warrantying a Duramax 2500 with engine failure that had a Banks Brake installed, even though the Chevy engineer determined the brake to not be at fault. I have heard no such reports from Dodge though. According to my reading so far, the instances mentioned are not dealer, but company based so I thought there might be a policy against aftermarket mods on trucks that has come about in the recent past. Since I love power and appreciate efficiency, I feel I would backslide in some respects if I traded from my current truck to an unmodifiable new pickup, so I wanted to inquire of anyone who may have knowledge of this topic. Thanks.

John,
Allot of what you speak is dealer preference/judgment. Ford as well as all MFG's to my knowledge, have always frowned upon modifications.The reasoning is that they supply a product with a waranty. If you modify something and your modification causes a failure, who should pay for it? The issue's you mentioned seem to be dealer related in that they made the decision before the MFG got involved. Basicly, they said no, customer payed, no waranty pay drama for them...

I believe the reason this seems more common to some is that car companies in general are not as financialy stable as they had been in the past. They are looking to reduce costs, all arround, and the dealer may not want to take the chance that they wont get payed. So, if you have an exhaust on the truck and through a rod, the dealer may initially deny waranty. If you were to push it, the tune will likely change(provided your mod didnt cause the failure). If you have a chip and throw a rod, forget about it, its your baby...

If you have ever driven your freinds 6.0L, I would be surprised if you think you would need the Banks kit on a new truck.. Unless you are a horsepower junkie /forums/images/graemlins/grin.gif.. The 6.0L runs like a heavily modified 7.3L in stock form.

If you go on most any diesel truck website you will see repeatedly: "modify your truck" & YOU are your own warranty station !!

I think that if your selling your trucks after so few miles and want the most for them, leave them stock. I am far more interested in a stock configuration when looking used then anything that has been modified.

So why do you trade your truck when it's just getting broken in? /forums/images/graemlins/wink.gif I think they'll have a hard time denying a warranty claim if the modification has no relation to the issue. But I wouldn't mess with one to save the hassle. I did most of my mods on my 97 Dodge after 100,000 miles.

My stepfather got used a superchips unit to modify the engine computer. It did provide 'power' when set for power.. but dod -0- for economy when set to economy.

The manual stated that you had to set the computer back to stock if you ever did need service from your OEM dealer.. etc.

Kinda funny huh?? /forums/images/graemlins/grin.gif

They tell you that it wont effect your waranty, but you need to return it to stock before you bring it in for service..hmmmmm. /forums/images/graemlins/wink.gif

I find it funny how these aftermarket companies always tell you they know more about a product than the MFG does, and that theyre stuff wont hurt anything. But, shhhhh!!, dont tell anyone you have it. /forums/images/graemlins/smirk.gif

Re: Modifying a diesel pickup--what\'s allowed

Unfortunately I have had alot of experience with this. The short of it is it doesn't matter who the dealer is. ALL the dealers are being clamped down on. And not because of money issues but because of what these power upgrades do. Regardless of what the mfg. of aftermarket tells you these trucks are designed by the mfg. to perform within certain specs. When you up hp by 50-100 and up torque the same or more what do you expect? That engine wasn't designed to hold up to that. And yes it does affect everything else. For every action there is a reaction. With the high sophistication of all aspects of the engine today one part relies on another.

Lastly to be honest the big three are all cranking out over 300 hp and 600 lbs. torque. That's enough hp to haul anything down the road at whatever speed you want. From a functional standpoint there is no reason to put anything on them. From a fun standpoint sure there is reason /forums/images/graemlins/grin.gif. But you can't expect to exceed hp and torque ratings and expect the companies to stand behind them. Plus with all the extremely tight emission standards it is against the law for them to work on vehicles that have exceeded those parameters.

Tom had it right. Leave it stock or forget your warranty.

Any mods I have done have been mainly for efficency and after the warranty ran out so no dealer issues. Even then all I added was a cold air intake and a 3" straight exhaust. No one around here even looks under the hood or under the chassis during inspection so I don't know about any "limits" on that end. I have inherited the gene from Dad that causes sentimental attachment to machinery. I still have my 1st car, a '73 Plymouth Fury III that my grandmother (yep, Dad's mom /forums/images/graemlins/grin.gif) bought new.
Anyway, I figure my 95 6.5TD chevy puts out a bit more than stock but I don't expect the transmission or rear end to hold up to much more. I don't understand needing 400hp in a p/u. I mean, Dad and I made a living w/ a 350hp Mack pulling 80,000#.(yes, I know...and lots more torque due to displacement). Point is, I hear these guys talk about how much their trucks can pull and how fast. Here's what I want to know... How fast can they stop that 30ft gooseneck full of heifers when its traveling at Mach3 MPH? Todays P/U's, IMHO, run out of brakes long before they run out of pulling power.
Sorry to get so off thread. You can stop reading after the first 3 sentences. /forums/images/graemlins/grin.gif

Yes,if you want to play you will have to pay.Fords bottom line is that the mod has to be the cause of the problem.Some say ford has to PROVE the chip caused the failure,but that also opens up their ability to charge you when they pull motor and finally decide that overfeuling and timing increase caused the hole in your piston.I also have traded every 60k for the last 7 years ford but this year I am holding on to my 04 350.I have never chipped my pwerstrokes but hands down this 6.0 will woup a 7.3 with a 50hp chip,and the tranny is incredible.Three reasons that keep me from trading is the big three have killed the used auto market with their givaways,I dont want to chance getting a sour 6.0 after I had the bugs worked out on this one and I am waiting for the 6.4.To be honest I really dont like the direction the three are taking with diesels,the emission thing is terrible and they are jacking the power up so much every year it makes these thing less reliable.I have been looking into the kit for the cummins superduty conversion and getting a fresh rebuilt 12 valve.I know the thing would feel like a turtle but it is way overbuilt for the power output and will run further than any of the new engines.Its the reason I started buying diesels in the first place until I got caught up in the latest and greatest.
