the drop in power is due to ecotec's being fitted with EGR valves, which are pretty much useless when you want to tune it because no matter what you do, you'll be fighting against it. the claim is that the ecotecs are more emissions friendly, which is rubbish because ive compared emission prints between my brother's car and mine (which has no emissions equipment other than a catalytic) and mine was actually better despite being 5 years older and almost twice the mileage of his.the ecotec engines are more economical hence the name and also the drop in power aas for which is better it depends what your after i guess hope this helps
Lmao I did that onceI know mines getting low when my engine rattles.
See I'm not sure on this, judging by this thread it seems it's common. But my old x16xe engine was fine. Although my new one burns through it like crazy.Are they meant to get through a lot of oil then? Or is it a problem with mine? I've heard different things from different people.
