hey all,

long time owner, new member here.

What is everyones take on Jet Performance mass airflow sensor and JEt Performance module?

I do not plan on putting in an intake unit, instead, just a K&N drop in filter.

 

Engine?

Model year?

What are you trying to accomplish?

 

2012 Expedition, looking to improve gas mileage and power without the loud air intake sound

 

Okay, what engine?

 

forgive me, was too early when i first replied

5.4 engine, towing package

Don't want to break the bank and don't want wife to know about changes yet want a little more power and better gase mileage

 

I highly recommend an SCT XCAL3 with custom tunes from 5Startuning.com (or you can PM Mike Butler at fordmdb).

 

Like said above I would recommend an SCT with custom tunes and I personally wouldn't waste the money on the K&N drop in, but instead get an S&B

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!

If you are comfortable and understand how to tune a vehicle, you can also do this yourself. There are several software programs available, that “Speak Common English” that will allow you to tune your vehicles ECM. One company is HP Tuners, they have a website….they offer two core programs, one for those who are doing dyno tuning and one for the home-garage mechanic (which is priced at about the same as most of the “canned tunes on the market) …this version limits the span of adjustments as a safeguard against doing something outside of the oem scope……basically, keeps you from doing something “too stupid by accident” (grin).
