ECU Flash, UNIchip, Osirus?
Does anyone know Whats the real differences between an ECU Flash, UNIchip, and Osirus software? And what are the pluses and minuses of each system/setup compared to each other in terms of power and efficiency?
Osirus is a flash type tune on the stock ecu. The UNIchip is a piggyback system. The pluses of the Osirus tune is great customer support, stock driveability, and more expandibility.
The unichip is one of the least popular engine managments for the car, and IMO outdated compaired to many other systems on the market.
It really depends on your goals for the car, and what you are looking to do. Talk to Jared at Uprev, he is a great guy and will answer any question you have about they sytem.

So out of all, the Osiris tune will would most likely be my best bet? I'm looking to have an extra jump in up gains wit small mods while maintaining everyday driving ability

Up Rev in Austin is the birthplace of Osiris. They have a shop here that will put you on a dyno and custom tune your car. The program itself is $400 and they charge $175 an hour for dyno time. They quoted me $700 total for the custom tune with up to 5 different maps (programs) I'm debating whether to do this now or in 10,000 miles when my warranty expires.
