Definitely needs a bigger header. Especially if it has TEA's nitrous port.

I didnt do the teickflows w the nitrous port because its a street car still and i dont want to use the nitrous that much but i would think there is not a huge difference in flow on 1 3/4 versus 1 7/8 headers plus we had the dumps open

definitely go with 1.7/8 headers if you're planning to add anymore mods.
Check TSP 1.7/8 great price and I believe its in-stock now.

I'm not a tuner I'm not sure if SD tune will gain or maybe get a better drivability.

Numbers definitely look low for the components. The 1 3/4 are limiting but that BIG cam should carry higher and make more HP.

Just $.02

Yea I just figured out that it did say 573 rwhp instead of 563 on the dyno graph but still under 600 I will report back with the new numbers after winter mods and changes are made and revised.
