This is not too shabby for a simple plug-and-play computer module. A quick shakedown cruise around the block confirmed the newfound power with a seat-of-the-pants feel. Our Ram tester was back to about stock before the big tires. Now we just need to get the intake and exhaust going so we can really up the ante.
