    328i 96' feels like its lacking power?

    Hey guys, I bought a 96 328i about 2 months ago. It's got 99,000 miles on it. Feels like it's lacking power. I've done fan delete, CAI, New cooling system, new CCV, cleaned the MAF, full new suspension, and some other stuff not related to speed.

    My 0-60 Time varies, but it's higher than it should be, Lowest I've gotten it is 7.5, highest is 9.5. I think my injectors are gunked up so I got a good deal on those and will be putting them in tonight... What else can I do to speed her up?
    It's Auto btw

    Personally, I'd suggest you start by putting the fan back on, with a new clutch if necessary. It won't make it faster, but it might make it live long enough for you to make it faster. Removing the CAI, and restoring the stock intake could make it faster, because CAIs usually suck hot air, not cold, until they suck in water, and break the engine.

    A chip/tune from a reputable supplier, like Turner motorsport, will be your best, most effective mod.

    Yea, Id say M50 manifold and tune are about the best bet, though that auto trans isnt helping your game.

    Have you checked the plugs?

    Yes i did the plugs 500 miles ago, I have a m50 manifold just need to get a few pieces of mounting hardware and i'll put it in. What stage tune would I use after that, for the Shark stage 3 you need new cams too right?

    Give em a call, I know that M3 cams can spice up an m52 very nicely.
