Well, needless to say I got a modified MSP and also a Unichip...its definetely not a user tunable ems, so if you dont have a Unichip tuner in your area that is also friendly enough not to charge you and arm and a leg, then its really not for you. But it does its job...its affordable if you think that it has a built in boost controller and its also plug and play (15 minutes), can be turned back to stock if needed in another couple of minutes, with no trace.
My experience is that when I had the stock MSP, it was impressive, I got so much power that it was great, its really what bit me to modify the MSP. Now I have huge intercooler, manifold, intake, exhaust, etc and the Unichip definetely needed a custom tune, I was spiking bad and also detonating from the extra amount of air. Fortunately I was able to upload a new map from Sam and the car is running incredibly strong, even at 6 psi I get torque-steer on 1st and 2nd which I never got at that psi level. My idle is almost perfect no more wondering on the air:fuel ratio gauge. steady around 14.5~14.7 no problems...I really wish I could get a dyno tune to fine tune it, but we will have to wait and see what happens in our area.
