I use predator on mine, and to be honest, I never heard about "cortex" so I believe you will hear only predator here, and of course SCT, but you don't have it, so...stick with the predator.

Side note - Try to settle on the one your local tuner uses.

I second the Predator suggestion, only because I use it as well.

Lots of the top tuners use it, so finding someone to write a custom tune later wont be hard, and downloading the emailed tunes to it is easy as pie.

You should be find though for what you listed, with the preloaded tunes.

Go with the predator.

Depends on your mods. Basic bolt on's, or going different blower or fully built?

It also depends on your tuner (example JLP, etc.), that's writing the new tune and if its an email tune, or getting you dialed in on the dyno.

back to the first post, just install a 6 lb'er from the start. A 4 lb'er doesn't add 4 lbs, its more like 2 since the HD upper is larger. You don't even need a tune to run a 4 lb lower it adds so little
