lift pump, if its stock straightpiped a bigger exhaust, ppe boost valve, depends on your power goal realy, if you want to hit above 400hp do trans upgrades or you will be sorry, tierod upgrade for boosted launches,
i would say fill out your sig so we all know for sure how to help better

don't go too much above the 500hp mark, the stock rods like to bend and that would ruin your day .

Yep, the next step would probably be transmission work... Have you thrown it into limp mode yet?
