Reviews: Jet Performance Products Performance Modules Stage 2

Definitely noticed a power, throttle response and shift points. Certainty helped towing as well, very pleased!!

live in michigan if you use 165 thermostat in winter you freeze and have high idle in neutral. Great product have run many years. I have 305 airraid spacer and cold air kit,granatelli mass airflow,flow master40 it runs pretty good. If i cant afford highoctane fuel its as easy as dissconnecting battery and a couple wiring harness and back to stock. dont be scared highly reccomend if you want the most.

I put this chip in my truck and everything is alot better the the acceleration the speed and the improvment in gas i woud recommend this to anybody

Woke up my 5.7 Hemi quite a bit. Very noticeable difference at wide open throttle. Combines well with my new cold air intake and dual exhaust set up.
