I have this in the for sale section, but of course local sales are easier. I have two custom tunes that can go with it from socaldiablo, and 2 mail order ones from RWTD. $200.
No, it fits only one tune. It was purchased in Nov. 2003. I am unaware of a Predator that holds 3 tunes. They don't have on listed on their site or forums. Are you thinking of the SCT Xcal 3, that holds three tunes? I purchased it merely for a way of uploading dyno tunes because at the time I didn't want to void my warranty with a chip. Funny thinking huh?
