Hey all, I've done a heap of research with little help, I boughg my wife an is200 recently and now trying to get some more power out of it, I don't want to go down the path of an engine swap so a turbo seems the best bang for buck solution, hardware wise it's a piece of cake and should be all done over a weekend, the issue i'm going to have is tuning, this I know very little about, i'm only planning on running very low boost, 5psi and a high boost of 7/8psi it won't yeid much in the power figures I know but it also won't blow the motor! What I need to know is, will the factory ecu handle a little bit of boost? And will it NEED a tune? If so what is the cheapest solution to this? I'll be happy with a 20/30 hp gain, any more will be a bonus, thanks for the help!
