September 5, 200619 yr I'm going to have an ECU upgrade from ZEDWOULD and would to know if this will damage the life span of the engine.
September 5, 200619 yr Increasing boost increases the output of the engine, which places more stress on it, which makes it wear out faster. As long as you don't go too silly with the boost you will be fine...
September 5, 200619 yr an ECU upgrade by itself doesnt change the boost - it just changes the fuel mapping [and also knows how to provide fuel for higher-than-stock boost levels]. Having said that you are probably having jets or an EBC installed as well, correct?
