Yea definitely lose the K&N, Ive lost 1 turbo to one already....Try out the ZooDad mod, and the 10k mod...The foil delete definitely made the turbo louder on my truck, but some people say it doesnt do anything....You can also try unplugging the wastegate, and than plugging it on the bolt on your intercooler clamp. It basically just makes your turbo build boost faster.
