HEY! we have the same name, except mine is spelled "Jared"
Anyways, SOUNDS like your Secondaries are sticking, usualy around 4 grand the secondaries are supposed to open giving that extra boost in power... Its fairly common for them to stick... Do you have a check engine light on? If so head over to a local Autozone, they will read the code for free, you get the code number, post it here and that could help a lot.
