    Hi There,

    I saw you mentioned Underground Diesel performance and was looking to possibly use them when I buy EFI Live and do a MPG tune and a heavy towing tune. Was wondering if you'd used them and what you thought? I have an 05 LLY Stock minus LBZ MP, MBRP exhaust, air intake so pretty much all stock.

    Thanks for the help,
    -Ken
