Well, I installed my Airaid CAI about an hour ago. Took around 45 minutes, with 35 of those alone. My first impression was DANG this thing is LOUD. Sounds mean as I don't know what! Well on too the road test. Sounds even better when you get on it! I loved the sound around 3k rpm(around there i think). BUT, the thing I noticed, and maybe after a full tank of gas my ECU will get used to it and fix this, but I noticed that no matter how hard i tried, I could NOT get my tires to spin. Before the CAI they would spin every so often in a straight line from a dead stop, and very often when turning. I havent tried to make them spin while making a turn yet so I don't know if it will spin them or not. So far I love it, I don't tow, probably never will in that truck, so the low end torque isn't a necessity for me, so I am not mad about it dropping any. I am 18 now, and like all kids I love the sound and look of things. The only thing I need to decide now is do I get headers? or the Unichip? I know what Gorilla will say Graduation money is coming in daily so it looks like one of those will be added this summer! WHY OH WHY CAN I NOT GRADUATE EVERY YEAR!!!!!
