I get better mileage with the 91 tune than I did with the 87 (when I can keep my foot out of it).

$100 for a 3865 is a really good deal. Are you sure it's unlocked? If not it'll cost you another $100 for SC.
Thanks for the info guys! and i found it in another state thru craigslist so i was kinda concerned about it being locked. but the guy seemed real nice and said i could come tune my truck first and then pay him to prove its not locked but then i had to break the news that i was out of state and asked him about shipping it so we settled on paypal and he shipped it out today so i trust that its unlocked... but like you said you never know with buyin used.. he did seem to be a good guy tho, even joked that i helped pay for his 10 year anniversary dinner with his wife lol so my good deed for the day is done
