Hi all. I've got compact from 2000 with 1.9 m43 105hp engine. For some reason BMW have done two same engines but with different soft and different horse power. There is 105hp version and 118hp version. Please tell me, if I chip my 105hp engine with the chip used for 118hp engine which gives gain up to 139 hp, will I feel the real difference? It costs about 100 quid to get it done and I just wonder if it's worth doing, what do you think? Cheers
