I hear MPI tuner is a really killer tuner! I have a cheap never used/never installed/in the box one for sale for 525 with shipping (costs about 700 from Modern performance)!
Sorry I feel like i am whoring myself out trying to sell this thing, but its a great unit for someone in your position.
Microtech, unichip, and MPI i think are pretty much the standards for people on this forum. Just remember that you get what you pay for.
