Automatic Protege5 Turbo question

[SylverSnow]

Quick Question guys, Im doing a bit of an experimental build with a buddy of mines. I'm just curious how much boost the stock p5 ecu will be able to handle. I heard that its about 4psi but i don't know if its true or not and would appreciate some feedback. Thanks guys

The stock p5 ecu can handle 0 boost. You will need an msp ecu to run this car with boost. And then you need a manual transmission.

The stock p5 ecu can be made boostable with a complete air fuel and timing piggyback controller on the automatic. Then you can run as much boost as you want.
