Review on Jet Performance 90904S JET Module by Shigg Bigbee

As previously mentioned, I received this module with very fast delivery. I used my main account but opted for 1 day shipping for 3.99 and was very satisfied. The installation was very easy (20 minutes) and explained in the instructions included in the package. The car I installed the module in (2010 Chrysler 300C) was tested before and after installation and let me tell you that this module does exactly what it says on the tin. Combined with an SRT-8 exhaust package, low temp thermostat and K&N air filter, my car was tested at 415 RWHP on a dynamometer versus the previous test at 368 RWHP. I'm not claiming that the jetting module did all the work, but as I said, the second stage module requires a low temperature thermostat, emissions enhancement, cold air, and the use of 91 octane or higher gasoline. The car shifts smoother, is more responsive in corners, and it becomes much easier to get onto the interstate. Acceleration in the range of 100 km/h and above is now easier. So it's a drastic improvement over the stock car, which was very good from the start. This product is definitely worth the money!
