I dont belif you can get 28 hp outta chip and 15 from intake. Most of E30 2.7 or 325E have over 200 000km.
That means the engine has about 100hp stock . I heard how mileage kills the hp.. I think 15hp outta chip plus 15 for inatke works out to 25hp max.The stock engine has 122 hp but as I said it goes down after many km. I think to trow intake and chip is ok but not sure how differencial mode goes.
