I had the torque curve one on y 91' It felt it could pull a house, and it accelerated a little better. I put he smooth bore on my 99' It feels like it pulls a little better and accelerates much better. I think the main difference (besides the spin on the air) is when the TBS creates the most velosity. The smooth bore creates it more from mid to top rpms, and the torque curve is more low to mid rpm.

 

im really curious to see how this turns out after i get this new throttle body with larger injectors (in the mail)

 

Does it have larger bores?
