If you have a ton of mods you'll not be able to use our Power Module. Our tuning is designed around a stock vehicle, no problem with a cat back exhaust or air intake systems and minor bolt on items. Premium octane fuel must be used no less than 91 and we recommend 93 where available. On our stock vehicle used for testing we gained approximately 12hp and 19tq additional power. The Power Module goes into the service port located on the end of the computer opposite where the wiring harness connnects.
Damn it I really wanted one too

You will have to pull your computer out and strip the protective "clear coat" off of the laminated board of the J3 test port. Ford completely disconnected the J3 port on some computers so even if you can strip the coating off to contact fresh conductor, the computer may never know it.

It is much better to get an SCT "switch chip" and have an SCT certified dyno tuner burn a few programs onto it. While its a little overkill for the mods you have, if you were to run a high performance camshaft or set your motor up for a turbo then getting some dyno time is worth the money/time.

The dyno place in chicago quoted me at 450 for everything dynotime sct tuner chip conversion everything. I am going to take auto body/ paint classes because I am going to repaint my baby. But next summer you bet you ass I am going

I didnt realize OBDI system could be tuned like that

 

[94 4.0 5-spd 4wd ranger]

ive been running the jet chip a while now. i have headers, full 2.5 exhaust, gutted cats, "upgraded"coil, ported throttle body, full 3" intake, and a mass airflow sensor from a 4.6 econoline van. oh and not to mention a 3" hole through the bottom of the airbox into the wheel well. the chip made it shit at hire rpms, along with the chip and the new ignition coil and wires the power is much smoother. truck seems to run better with the chip

i actually bought a hypertech power controll module for my 94 ranger with 4.0, (which is for sale on craigs list by the way, its brand new) spent the money just to test it out and after a week i started my v8 swap so have no use for it anymore... contact me if intersted in (part# 648711)....
but to answer question i did notice some positive improvements in performance so no complaints. when i called hypertech they told me the same thing word for word

I had a jet chip on my 94 2.3. It helped a bit, with some other mods like you mentioned (exhaust, intake, high flow mass airflow sensor) but on a 2.3 theres only so much to gain. On a 4.0 I would imagine it would make a difference, even if it didn't, knowing you did it will make you think its better. Depending on the price, I'd say a 10 hp gain for 200 bucks would be a good deal if you don't mind running mid and premium grade gas.
