    a lot of aftermarket exhausts zap power on bm's, i would only ever consider 1 if it was eismann, ps the 3l m3 only had 286bhp. that was bigger cc and a lot of trick bits and pieces. ps, was the chip set up to give the car the best possible results from your mods? or was it just plug and play?

    hi mate

    So it's 193bhp standard and you got 213bhp? The chip gives you 10bhp so from your cams, exhaust, filter and throttle body you only got 10bhp?

    Somthing seems wrong here, I herd that just adding the throttle body takes the 328i over 200bhp?

    Hope you get it sorted, Like others have said I'd be looking at around 230bhp, pitty you didn't know the bhp output of your car running standard in the first place. I know the book says 193bhp but it might of been down on power due to age or servicing etc...? Then you would of seen exactly what what bhp your mods gave you.

    PS I would of came along for a look at Dastek when you were getting it tested, it's not to far from me.

    right chaps diagnostic done on autologic and the only fault code was asc sensor.
    all other sensors etc totally fine.
    also did a compression test and the figures were as follows-

    5 cyl all reading 11 bar around 160 psi
    1 cyl 10.5 bar 155 psi

    I'm sure i read somewhere that factory spec was 10.2 bar would that sound right and any thoughts on compression? are these figs the norm?

    I'd be curious to know the factory specs for the 328i too, because I got about 205psi across all 6.

    So either your down on compression (which could explain the power), or i've done my test wrong, and I need to do it again correctly.

    That amount of compression is totally fine and isn´t going to cause a massive drop in power.

    if that is about the norm with regards to compression on a nikasil block running fine & dandy and i'm sure there will be other cars running better out there then i can only put it down to a poor tuning experience.
    got a very helpfull pm from someone in New Zealand of all places !!! who has advised the afr should be 13.2 right accross the rev band until almost peak where it should richen up slightly.Apperently his info came from the Dastek founder Peter derweekt or something like that.

    it does sound like the car needs tuning! maybe the chip hasn't been set up correctly? or even try a different rr to see what they get!

    There are no AFR must be this rules.

    So anybody reading this, don´t ever EVER believe such information.

    I would say a healthy block would be in the 170-190´s.
    But even so a steady compression across the board is better then varied as that is more likely to suggest problems .

    I think it´s the tuning.
