    1. Yes I have a STI now.
    2. So according to the chart, it looks like it's only putting down 220whp/215ft/lbs?

    That's the problem with dyno charts; they are all different due to temperature, operator inputs, and dyno type.

    In this case the dyno is a Dyno Dynamics, or a "heart breaker". They always read low. 210-220whp is decent for a pull on a DD. On a DynoJet, most people get 240-260whp with their STi's (with 260whp being exceptional.)

    Dyno's should only be used to measure increases (or decreases) after modifications. They shouldn't be used for comparing to other people's dyno numbers - at least not unless it is the same machine, location, temperature, etc.

    think of it this way, would u rather have lower, uncorrected numbers or inflated, higher (corrected for certain variables) numbers? Most aftermarket companies use the latter for better hp numbers for obvious reasons.

    I think you need to start a new thread, or post in a newer one.. rather than digging up something from nine years ago from members who are no longer active on the site.


    (260whp sounds about right)
