It seems all or near all chip tuning ECU or box mods, basically follow the same path by altering the fuel air mix curve from the manufacturers standard setup. having watched some Youtube runs by claimed 200 or even 275HP 1.9TJD 147s near all show excessive black smoke from the rear pipe, indicating it's either got a screwed up phased and calibrated injector pump or maybe some odd problem with injectors, although doubtful. Anway with tuned chipped (D) engines it's a classic sign it's probably been messed with. Working on that premise, my little 147 smokes like a chimney and pulls like a train, not that it tells me what the BHP is only it's probably been messed with. The guy assures me he had the car standard at 120HP, gave it someone who remaps ECU's for race cars, and when he got it back some 2.5 years ago now it was night and day different, but has no idea what the BHP was or is as it's never been on a rolling road. "Costs I expect". I have never been in an Alfa 147 of anytype prior me buying this one, so I have no experience reference point; I also feel paying out 80 or 150 pounds for someone to give a paper to say it's standard at 120 HP or 350 HP LOL. or something, is not worth the money, can't afford it anyway. So I need to find someone local with a normal 147 TJD 100 or 120Hp to personally gauge if it's mildly more powerful, mind blowing tuned, or just warmed up a little, whatever that is. The box chip will only fool the system to pump more fuel/air, as the guy said, if you plug it in and there is a power reduction it's way above 145BHP without the box MOD, if it's standard I should be pleased with power increase from 120 to 145 BHP and if say it's 140 already you will notice no difference in performance. So, in summery, the little box MOD, if nothing else, is going to tell me if I have some 175 or 190BHP type remap or a mild tune, or standard. that's the logic.
