Nothing major.. gutted the internals of the airbox, removed the MAF screen, and running a 3" dryer duct from under the front driver side fog lights into the airbox, will be probably changing to a 4" dryer duct. I was going to go witha CAI system, but I'm too lazy to have to remove it every season because of all the snow
. At least with the dryer duct if it rains hard or snows.. all I have to do is push the duct up more to behind the bumper. 180 T stat. I am planning on changing the SC pulley, but I think I will do that after I get a Trans cooler first. ( no point modding the car if I don't think it'* going to hold up even though I have a 4t65HD tranny
, better safe then sorry.. pushing the big beast home would not be an idea of fun
ha ha ha ). After the SC pulley, I will do a cat-back system to support the NOS I eventually would want to dump into the Beast.. and if I still get my *** handed to me then.. then I'll just have to fake a NOS leak in my cabin and laugh all the way back :P .
