it cost me over 1500 to delete my 6.7, i was buying mine at napa prior to the delete and tuner. its not expensive enough to justify the tuner and exhaust kit. not even close.
ive been told that some companies will not sell the delete kits in the usa due to pressure from the EPA. i dont think i will tune the next one, my milage has not gone up drasticly and the power was crazy even without the tune. and i could have bought LOTS of DEF for the price i paid
when you say "someday" remember its just code for "never"
