The Unichip is nice and I'm considering it in the next couple months, but I'm leaning towards the MPI because even though it requires some tuning knowledge (which I'm working on) there's a ton of support on this forum. Going to the UC tuner isn't a big deal, but when you consider that buying an Injen CAI is $200, it'll cost what, $100 to tune for just the intake? Then add a FMIC later down the road and on top of the cost of the IC you'll need to tune for that and so on.... After a while you could've bought a stand alone, or the MPI and injector set. If you're happy with your current mods with one or two small ones down the road, then I'd be all over the Unichip. If you're looking to build your car up more and will be constantly modifying Emanage or MPI is a better chioce.
