I'm doing a custom kit, and it's going to be ALOT cheaper than the $5200 Tom charges. I have someone fabricating the turbo manifold and tubing for me, Tom's kit is a waste of money and not worth the price... but it does get you the numbers.
I'll definitely have to take a look at Dyno Daves. I've never even heard of him, but I know a few guys that have friends at Rousch. I'll ask around, thanks.
And Tom is making 435whp.
