Hi I have a ek with a b16a sir Jdm swap into it and this week I have bought a skunk2 intake manifold and a skunk 2 70 mm throttle body and I'm about to install them . will I need a tune for these or everything is alright ? will there be an disadvantages to this mod? the car at the moment is a stock motor with aftermarket exhaust manifold, better spark plug wires , stage 3 clutch, lightened flywheel and still on factory fuel. I just want to know if it is going to be safe to run these without a tune and if they will give any decrease in performance. pls help
