TPI or SuperRam etc.?

For now I'm just going to be street racing and I was wondering if staying with the TPI and just upgrading it with like throttle body, air foil, K&N Cone air cold air system, and all the SLP stuff. Lemme know what would be better, staying with TPI and upgrading it or go with something else like a SuperRam which is 50 state legal!

The stock 48mm TB can support a lot more power than you'll need with a TPI. The airfoil is just a waste of money, and well, the K&N is a good idea.

The SuperRam will help quite a bit, but it's obviously quite a bit more expensive than your other mods.

I would go with exhaust, headers, catback etc. That's the first mod, hands down.

Upgrading to a larger TB will be a waste of money. I would upgrade the TPI base and runners or get a whole new intake manifold.

I disagree, the airfoil helps smooth out the air and reduce turbulence. I think it's a good idea.
