If you have yet to get to a dyno, haven't had access to a reliable wideband, or have not gotten any logs.......I WOULD BE VERY CAREFUL trusting a mail-order tune
It's not to say you can't go that route but it puts more of the liability in the owner's hands to do just as i have rec'd.
On my old cobra i did a mail-order tune and he said he'd do a race tune for me as well but that required loading a map and testing it on the strip, reviewing the logs, and trying again and again until done.....that still required a wideband though obviously.
