hello, there are for the astra f 1.4 two engine variants that a 1.4i the eu model with kat and 44kw den si without kat (for the Swiss market) with 60kw my question or questions are now (of course only hypothetically seen) if one would have to remove the kat with the eu model to get to the 18ps extra power also the control unit from si use or can the control unit from the eu model so out of list e.g. disconnect the lamda (which, however, has the consequence the control unit i n the emergency mode changes) that it would have the same effect since I only pose this question hypothetically as I said, please refrain from moral statements (as I know it is not allowed in the stvzo) and would be very grateful for detailed technical assistance
