performance chip's for the 4.0L

[BrodyPaul]

I recently bought a 2008 ford ranger fx4 with the 4.0L SOHC engine. I really love the truck, and have spent a lot of time and money in the past couple of weeks adding all the things I wanted to make it a perfect truck. which brings me to wondering about adding a performance chip to it. As its my daily driver but also built for the bush I am looking for any suggestions on a good all around performance chip, something that will boost the power when I want it but also can be tuned for economy. I don't know anything about performance chips and it seems like there are a lot of options on the internet. I was wondering what others have read or used for this particular engine and year range of ranger. I appreciate any advice you have. thanks

I have a 4.0 OHV, and I just bought a JET module. Should be here today, I'll let you know how it goes.

I’m curious as well, as I have a ’92 4.0 Custom. By the way, how’s that K&N working out for you? Been thinking about picking one up.

I switched back to a regular Wix filter. I like it better

So I just took 'er out for a spin. I noticed a difference, but not a big one. It smoothed it out a bit, doesn't lug as bad in 4th @35mph and 3rd@25mph. Power band seems to be smoother from a roll up to about 75 is where I stopped, but I don't think it was any faster...

Exhaust sounds smoother, more of a purr than a hacking dry cough.

I think all it really does is refine the software enough to give back some pony's that've probably been lost with age. Put some fresh pep in the step of an old truck.

I wouldn't hurt yourself to try and buy one. 'Specially not at their rates, and not for the cheaper price on Amazon either.

I'll report back after a few tanks and see what the MPG's are.

Also, I should point out that, when installed correctly, the chip is sprung against the computer case and interferes with the computer mounting bracket.

The cool thing though is if you install it backwards, it fits, but the fuel pump doesn't run.

For anyone still keeping score,

I haven't been able to get any reliable/consistent measurements, but I'm certainly not putting up hybrid numbers. Maybe 1 mpg more, but, that's about it. Still convinced it has more pep, but again not a mustang boss by any stretch.

Or maybe you need two chips?

Does it work like that?

With the 4.0 SOHC engine, it is easier to get a programmer to reprogram the trucks computer. You don't have to mess with installing it and making sure you have good electrical contact. You just plug it into the OBD II port and follow instructions. You can always go back to the factory tune if you want to. I do when I go in for emissions testing.

The important thing is to find programmer that knows how to get the best tune. Most of the generic tunes don't give much improvement. I don't know who to recommend because the guy that did mine no longer does it.

For anyone still keeping score, I just did a pretty mixed hwy/city tank. Stop and go lights 0-30, stop and go lights 0-40, a few good stretches of 65mph interstate, and a 2 hr stretch of 20-30 mph traffic jam in 40 mph wind.... Totaling 195 miles, I filled up for 10.5 gallons. Giving me 18.5 mpg. Spark plugs gapped at 0.060 with a speed demon pack and the jet chip. Better than I thought I would get, but again nothing special. The best I've done without the chip is still 22.5.

Man, what a great tank that was....
