The only thing needed is the aeromotive fpr 1:1 which you can buy anywhere and longer bolts since the HRC spacer in between the head and intake manifold makes the stock bolts useless. I had the ones that came with it, but 2 or 3 broke so i just bought bolts from lowes and fixed that issue. Everything else is included, the same things that came with the kit. I used the portfueler up to 15psi, it felt good i never had any issues besides when it came from HRC tuned for afr's in the 8-9 range which is wayyy rich.
