Not sure what your asking, but like what Matt said below we need to see whats going on before we can answer your question...

Yes a 4cyl turbo'd car will feel "slow" till your spooled, so thats what I'll have to assume is going on... Is there any engine management on it at the moment?

Turbo lag. You're driving a four cylinder economy car until the turbo receives enough energy to say otherwise.

I read somewhere that the utec utilizes the factory mapping until 2500rpm, then kicks into its programed maps. ... is this true? If so it could be why things are funky till 2500 and then improve.

For clarity, when you say it drives like crap, is it that it's sluggish, or does it buck, or otherwise run not-smoothly?

Your profile says an '02 WRX, what mileage? I'm wondering if there could be something else going on, like the IAC valve.
