Going Boosted - Toyota Yaris Forums

the only reason the piggy backs don't work, is cuz u guys are afraid of a check engine light... just remove the "learning" curve of the ecu by removing one of the o2 sensors and your good to go (I don't remember which one), thats the way mine was done with the emanage... i doubt your car would pass inspection anyways, so a CEL is no big deal.

as for the gauges, if its tuned right you don't really need any, but just to be sure, I installed a blitz turbo timer dc IV, it is a turbo timer and a boost gauge, just to make sure i didn't overboost. The only other thing to contemplate is a wideband o2 sensor and gauge to be sure your air fuel ratio is right
