Jet2 Performance

Intake, injectors, ignition coil, wires, plugs and new radiator were leaving me with a Check Engine Light and 12mpg. (I have 31" tires) The Jet2 tuned my engine right and now I'm getting 16mpg and my CEL turned off. Probably was running too rich through the O2 sensors, problem solved!

Wouldn't purchase

I had an issue with the product I purchased and wasn't satisfied with it because it did not deliver what it advertised. I was able to refer my problem to a manager by the name of Mr Arriaga and he was extremely helpful and was able to keep me as a customer. I will continue to do business with Auto Anything and continue referring my family and friends. This is a company you can trust. Thanks.

No noticable improvement

Easy to install, but really have not noticed a difference. In reading the Jeep Forum posts others have not experienced any improvement either. I'll have to wait and see if there is any improvement in gas mileage.

This had a great result which I had delayed trying thinking it would not measure up. My change was substantial in horsepower using the stage two tuner on a street 4.0 6 with Banks intake, headers, and an oversize exhaust. This brought all the pieces together, and I have not yet installed the 180 degree thermostat. Will see what impact this has in addition.

The chip has made a big difference in the performance of my jeep, that also has a K&N cold air intake system, 1" billet spacer under throttle body,and a magna flow performance cat followed with a flowmaster delta super 40 muffler.

Not the best product in the market. I could not tell a difference at all in horsepower and I could not get my Jeep to stop sputtering and hesitating with the chip installed so I finally just took it back off. Also my check engine light finally came on and my Jeep then shutoff on me. Don't know why it shut off but that was the last straw. Im sure this product would be better on a newer vehicle rather than a 1996 Cherokee.

This Is My First Purchase Of Any Jet Merchandise. Easy Install....Well.....Except Changing Out The Stock Thermostat To A 180 Degree One, Which Is Required For The Stage II Module On The 4.0 Straight 6 Engine. That Seemed To Become A Major Ordeal For Some Reason. We Will Call That "SGS" ("S"tupid "G"uy "S"yndrome). All That Aside, Everything Went Fine. I Started The Vehicle Up After Install And After Warming Up For A Few Minutes, Immediately, I Noticed A Definite Smoother Idle. I Also Noticed A Definite Cooler Operating Temp On The Dash Gauge. After Driving Fairly Conservative For About 8-10 Miles, I Did Some Harder Accelerating From Stops And On Entrance Ramps To The Interstate. They Was A Definite Improvement In Acceleration Thru The Whole Powerband And The Throttle Seems Much Snappier. Now, Don't Read Into This Too Much. This Is Not A Mind Boggling Change In Performance, But It Is Noticeable. I Have The Banks Power Torque Tubes And Monster Exhaust And That Install Improved Performance. I Installed The Banks Power Ram Air System And That Improved Performance A Little. I Installed An Aftermarket Throttlebody Vortex Spacer And That Was The Least Noticeable In Performance. I May Try The Jet Throttlebody Spacer To See If That Is Better. Soooo...........What I Am Saying Is Every Little Enhancement Helped The Performance. It's Too Early To Tell About Gas Mileage. I Recommend These Type Of "Bolt On" Upgrades Over Tearing An Engine Apart, Changing Heads, Pistons, Cams.......Etc. I Purchased This Jeep New 10 Years Ago And Kinda Babied It Over That Time. I Also Installed New Fender Flares And Body Armor Just As A 10 Year Birthday Gift To The Jeep As With All The Above Installed Items.

great product
