ok I installed the cams and I dont know about the stock ecu handling them because I had to mess with the aem fic to idle and not have flat spots in the throttle. The high end power is unreal tho it pulls very hard all the way through redline. Idleing the car pretty much sounds the same just alittle rougher and my exhaust def. got louder. I will have to get a better video of the exhaust. The one I took was crap
