    Default Tuning box only giving 158bhp/275ft lb

    I've got a 54 plate cdti 150 and put on the rollers with a caterman (or what ever its called on here) tuning box expecting to get around 190bhp/320ftlb and it got no where near. I took the tuning box off and the car made 143/225ftlb which is not far off standard power meaning there is nothing wrong with the car.

    My question is why is the box only giving me an extra 15bhp? I'm happy with how quick the car now it only means that with a proper map it'll be even quicker but where have people got their power figures for the caterman box? has anyone got any proof of a car making 190bhp with one?

    the box has been on for over 30kmiles so could it be knackered? I'll put the graphes up in a bit but the curve of the graph is pretty much i dentical with and with out the box but just with extra torque and power.

    I've got a feeling there will be a lot of people driving round with less power than they think they have.

    It does mate. with out it actually ran 145.3bhp which considering the egr hasn't been cleaned in probably over 30k miles or more is a good figure.

    Mine was kicking out 165bhp and 240 lbs/ft as standard, without me ever having touched the engine, cleaned the egr etc and having done 60K miles...

    Red is with the tuning box green is without so it copies the same curve with both.

    Its only supposed to be 150bhp so its near enough right each engine will vary slightly but as the graph shows there is an increase just not by the huge ammounts quoted by people i have read about. I only found one more power graph shown on here and that was for a bbr remap (?) and that obviously did have 210bhp/320ft lb.

    It just shows that proper remaps are deffinately the way to go. Or unless anyone can produce a graph to prove that the tuning boxes can produce that sort of figure.

    Probably is which is good news for me as my car can only get faster.

    The power is very consistent and you can see that the torque is in a big lump around the 2.5-3.5k mark then dies off. With a remap it may produce torque across more of the rev range
