I am looking at purchasing a diablosport power tuner(used but good condition) for about $100-$120....I know these things are pricy brand new. I think it is worth it...do you? I have a 2000 lightning setup. ALso, do i still need to chip it, or just lug this tuner in and play?

 

hmmm for a used diablo tuner you might want to check ebay everywhere else usually sells new products, and it doesnt need to be chipped you just plug and tune.

 

I do not have a lightining but I have a 2002 4wd truck with a diablo sport programer and I love it.. And I got mine brand new for 319$ so 100 is a pretty good price..
