Im buying used steeda underdrive pullies and a used diablosports predator tuner for 300 shipped, good deal?

Also does the diablo come with a tune or would u have to buy them? I know if i want it custom i would have to buy it but just a generic 93 octane tune?

are they hard to use? worth it?

I'd say so, make sure the tuner is not still married to the guys car you are buying it from. It comes with tunes already preloaded.

It comes with just a regular diablo tune and from there you can adjust some parameters. I felt a little bit of difference but not a ton. If you advance the spark on the tuner you will feel a little bit of a power increase.
Diablo's are very easy to use IMO.

advance the spark??

should the engine be advanced or retarded

You won't have to do anything to the engine, it's just a parameter you can adjust with the tuner that you will give you a little bit more of a punch.
