I think I understand turbos and their theory fairly well. But, there are a few questions I have when it comes to installing a turbo on the new fuel injected Phazer. It has been mentioned that the Yamaha FI system is blind to A/F ratios because it only uses air temp & density for it calculations; no EGT or oxygen sensor. I know a lean A/F ratio will produce more power but bad things happen as a result.
1. Will the stock FI computer recognize the added boost and compensate?
2. Do turbo companies have a different computer or add-on/piggyback computer to allow more fuel?
3. Will the stock injectors handle the added requirements for 130-140hp?
4. If one were to install a turbo and do nothing to the fuel injection, what would happen?
Thanks for any clarrifications you can provide.

250hp is about all you can get out of stock fuel system

It's a Phazer. I don't think you'll be getting 250hp out of the stock fuel system.

All aftermarket turbo/supercharger/nitrous systems come with some sort of fuel upgrade to match added air, the stock injectors are adequate in the lower boost kits and if the manufacturers where to produce a High boost kit they would provide larger injectors and fuel pump.
Yes the EFI kits come with a piggy back fuel controller.
