2005 Explorer which wayto go -hypertech or...

I get terrible mpg with my 2005 Explorer. I am planning on changing the plugs and wires, but I was thinking of getting a Hypertech Econ chip, or maybe just getting an HP Tuners programer, or an SCT, or something else. What is the best way to go from your experience here?

I talked to mike at 5startuning.com. He was pretty cool.I told him I wanted to try to change the plugs and wires first. He agreed. I pulled the plugs, and they looked bad. I replaced them with double platinum autolites, and already I'm getting over 2 mpg more just around town.The dealer where I bought the truck, used ,about a month and a half ago said everything was OK according to their computer. I guess all it said was that the plugs were firing. Big deal. So much for dealers. I still might try the SCT X3. Mike sounded confident it would help, and i've seen alot of good things about his work here.

go with the xcal-3. You can have different tunes like economy and performance. The tunes files should change transmission shifting too.

Ralph, did you get anything yet?

I am also looking for suggestions for my '05 4.6L. I want to chip or flash my ecu for increased performance....but would also like to be able to easily switch to and run a stock (economy) map. Right now I'm considering getting an SCT 9600 livewire.

I never did do anything with this. I figured I'd just put up with it. The best mileage I ever got was going down to North Carolina to pick up my son's stuff when he graduated college. I got just over 20 mpg on the highway with the truck set on cruise at about 70 mph. Not too bad. Around town still sucks at about 15 mpg. At this point I will either just keep it until it dies ( only have 80k on it), or I'll sell it and get something else very soon. Just retired from Caprenter's Union in December and don't really need this. Good luck to you.

With regards to “Chips” and “Tuners”, years ago it was the best that most could do to enhance the ignition timing, fuel curve, transmission shift points, etc. It was (and still is) very important that a person verifies that the “Tuner” is ASE certified in both ECM and Transmission programming and IMHO be have current certification by the OEM whose vehicle you want to modify. There are plenty of persons who advertise their programs to be the best and even offer custom tunes, but in all reality, very few actually have credentials in these areas- but that’s not to say that some of these “geniuses” haven’t really caused damage to a few vehicles- just jump over to flatratetech.com and read just some of the comments from the MSE techs!. Perhaps what is equally important is the parameters that can be adjusted are set by the oem vehicle software…so there is really no “magic” in what they are doing anyway.

IMHO, if you live near any major city there are excellent tuning specialists with dynos who for the same price (if not less) will tune your vehicle taking into consideration your specific needs including environmental conditions, for your specific vehicle. IMHO, the best bang for the buck!

I also own a 2003 Corvette. I had a mechanic that is very well-known and respected in my area install a different gear setup in the differential, and change the exhaust to a free-flowing type. I had already changed the intake to a ram-air type configuration. They did a computer program change to account for the different gear ratio and air flow.The mechanical work was fine. However, the car ran like crap. They looked at it on two separate occasions after the initial work and reprogram. Finally, I brought it to another tuner. He spent several hours working on my car. Now, it shreds tires at will, shifts flawlessly, and does just what I want. The point is that a good, experienced, knowledgable tuner can work magic on your vehicle. You just have to find the right one.
