do i need to do the 10k mod since i got a TW?? I heard that it wont effect it... Can a SD do the shim mod?? I am on vactaion and bored so i need to do some free tweeking to it. i just cleaned my ebpv tube. its fills full of soot and they said clean it even if your ebpv sensor is unplugged cuz it might help with mpg?
