Use what you have a save some coin. Look up a guy buy the tag name "diablew" or 06montess or something like that. He can get u hooked up with a custom tune thru ur hand held and will be much better than the canned tunes that come in it. When i had my diablo preditor i had him do a custom tune for me and it was much better and i instantly noticed a difference. Only reason i changed tuners was because the old preditors had no tcm support and i went with nitrous so i wanted it to be tuned in person/street tuned. But for what you are doing ur intune will be fine. You can even do data logging and send it to him like you would with an autocal/efi live.

i thought about letting them do a custom tune on it but i wasnt sure if i would be getting the same results compared to other companys
