Something isn't right. You should be over 500hp with that setup. How much smoke do you have now?
There's a chance that just losing the Swampers would cause you to dyno 40-50hp higher! I bet you're making the power, it's just not showing up because of the heavy tires and such.
Of course, you could always go EDM (mach 5s) and pickup some power.
If you're running Pius' USB, then maybe just slip a Big Brother underneath it?
Why is it to weird to me to see a post like this coming from you, Cliff?
