Sounds great a) if you know how to set it up PROPERLY (remember manufacturers spend many many months dyno and road testing the cars we drive with huge variety of expensive gear) b) you allow enough budget to buy enough decent roller time to do so!

I personally would have no worries, but I am not you!

How much?

Well $660 from an engineer at U.S Rally Team which also includes boost control w/solenoid. It comes with software to work on mapping via laptop plus a suitable harness. It seems it has allot of potential as well, can't see any reason why I would need to replace it in the future plus I should be able to fit it to pretty much any car with an ecu as standard.

That can get tricky. ECUs on a lot of cars control various other bits besides the engine, so you may end up needing to leave the old ECU in place and trying to get it to live happily alongside the aftermarket one. Things can get very complicated.

Cheers,

Colin.
