Not much HP just sound, if you want HP and quick acceleratino from idle stop to top end. Then go for these mod's SK throttle spacer, JLT oil separator, JMS PedalMAX, SCTx4 87, 91, 93 tuner direct from SCT Sanford, FL it let's you adjust RPM's range including redline, shifting firmness in auto trans, turns off rev limiter. All these mod's will be around $900.00. These are the mod's I have on my 2015 V6 Premium auto and in 5th at 2500 rpm's it leaps foreward with no lag what so ever.I have a 2016 3.7 and already installed a airaid cai and have BBK long tub headers and the short catted mid pipe ready to install the rest of the car is stock. It is a automatic. I am wondering what i can expect from these two mods sound and power ?
