    Be more specific: Does not make sense other than just getting heat soak after driving around for a long time and you're noticing that.

    ok sorry, the thing is that when I just started the car it feels more responsive and the turbo charges stronger but after a while of driving it, the car starts to loose power. Mabe I am geting heat soake, because I am using the turbo without filter and it is neear the manifold. How does heat soak feels?

    Get a filter on that thing before you destroy the turbo! that thing has a good chance of eating a rock, especially if its bottom mount.

    as far as heat soak issues.. i am far from all knowing but i thought of something that might work or might not.

    have you ever had the car on a dyno yet?

    i was thinking with a heat soak issue the car will most likely put out less power when experiencing heat soak.

    maybe if you have the money/availability of a local dyno bring the car there and dyno it.
    once as soon as the car get to a safe enough operating temp for a full boost pull
    and then once after the car has been driven for a while?

    see the results

    just a thought, like i said i am no expert
    if this post makes no sense, just call me an idiot and i will delete it.

    has it always been like this? could it be that its running lean (and therefore running fine on warm up enrichment?
    could it be temp sensor related?

    the intercooler is really big, and the turbo is a gt28rs garrett. 0 lag. I am boosting around 0.5 bar
    this problem only happens sometimes, and if i accelerate it en neurtal the problem goes away like 10 minutes and then it startes again.

    First off, can you please describe your setup, including software, MAF, exhaust, WG, BOV, etc.

    Stock FPR, stock ECU, stock MAF, and I'm assuming stock injectors.

    You need something to control how much fuel goes into your motor buddy.

    a after market fpr can do the job? For the moment I don't want much power, I want like 6 psi.

    Good luck with all that...

    Get proper injectors, proper tune, proper MAF then let us know.

    There isnt enough head room in the stock ECU to cope with that much boost. Some cars their is enough to get a low boost setup on the stock ECU - not so in the 6 cyl E36's

    Your going to want to buy at minimum; A wideband O2 sensor and gauge, and some form of engine management.
    I hate interceptor computers as they advance timing as they add fuel (bad for boosted motor)
    Get yourself a good management system now and you wont need to worry about it in the future.
    Fast, Cheap, Reliable - Pick any two, and the third is laughable

    It will be easier to find a tune if you convert to OBD1, but TRM is a starting point.
