I was reading that periodic reflashing of your systems computers by your dealer will negate any power enhancements you've made. Just how is this possible. Naturally you'd remove any plug-ins before you took it in for any type of svc, except maybe injectors and you certainly wouldn't remove a tc/vb before you took it in. Can any body explain this to me. Especially reflashing the PCM for auto/transmissions. I think I have that right?
