I have a jet module for my truck. I have had it on before but not very long at all. I have heard a lot of negative things about it. Like I said I had it on for maybe a 1/2 month and it didn't throw any codes but can someone help inform me exactly what it will do damage wise to my truck if anything. I haev a 2007 QC Hemi 4x4. thanks for your help.

 

It just doesn't do anything. It wont hurt anything but it does notthing. Sell it on craigslist and buy a SC 3865. There is a SC for sale on DT for 280. Thats a great deal.

 

Agreed, JET chips are junk. They used to be one of the only chips out there for vehicles newer than '96 but todays chips/programmer totally re-write the pcm and ecm for a noticeable power increase! Throw it in the garbage!

 

it won't harm your truck at all, it doesn't do enough to the tune to risk hurting the engine. You are much better off with a full tuner, like a Superchips though.
