I just bought a diablo predator, mainly because I am going to get a 75 shot in the next 3 months or so.
My question is should I use the tuner now and program everything, or should I wait to get the nitrous before I use it?
I have no idea how to use the tuner or install the zex kit I am palnning on getting, so do you think my best bet would be to take the tuner and the kit to a shop and just tell them to go at it? Or is using the tuner on my car easier than I think?

 

use it now and then use it again later. that is why yo get a programmer as opposed to a pre-programmed chip.

Have you read the instructions with the tuner yet? seems to me you just run the desired pre set.
