Dyno test : 2008 Dodge Caliber SRT4 before/after with Mopar Stage 1 upgrade

A friend of ours who’s stationed in Iraq with the Army has asked us to take care of his car while he’s overseas, and install a few performance goodies.

One of the first things we installed for him was a AEM air intake, which gave a nice gain in performance and throttle response.

We also ordered a Mopar stage 1 upgrade, and we decided to dyno test the car to show the gain in performance before and after.

Throttle response was really improved!
Boost was increased from 10-14/15 psi!
