Default Any Advise On Power Chips

A friend of mine, ok, an aquaintance, every one knows I have no friends... anyways, this person was asking me about putting a power chip on his Ford F250 (I believe 2002 or 2003 with 5.4), would be inprove enough to notice it pulling an 8500lb camper?

anyone?

Bueller?

Looking at it from an engine tuning standpoint, you haven't physically changed anything on the engine.

So, really, it can only do two things: Adjust Timing maps and Adjust Fuel Maps.

Basically, its going to richen up the mixture a little primarily during WOT/open loop, and give a few more degrees spark advance, requiring premium fuel, depending on the chip/programmer.

Its not really going to help at all during the cruising periods that you spend most trailer towing at, where he's probably struggling on grades and in wind.

In performance applications, its more worthwhile. I'm even working on writing & burning my own ROMs for my Honda this summer.

Bottom line, 8500 lbs is a lot of trailer. Too much, IMO, for a small block to pull comfortably...

I have a Superchips programmer for my truck. I like it and feel that it made a difference. I had a JET chip for my ram when I had that and it was a piece of shit, the only thing worse was their tech support.

Mopar Performance computer in my Ram and it made a difference. I heard nothin but bad news when it came to chips and I got the computer in a trade along with some other stuff. I guess you're bound to see a difference when you replace the entire ECM.

Don't try and run 87 or even 89. Misfires and spark knock. On premium it's like a whole nother truck. Biggest difference I noticed was that I use half the throttle I used to to get up to and maintain speeds. The truck doesn't need to downshift from OD anymore to maintain speed up hills.

If you can, find an actual factory performance ECU. If it's just a chip that connects in between the ECU and the harness... don't bother.
