So I’m going from a gen2 2.9 to a gen4 2.9, both standard inlets. Wanting to keep the 24/25 lbs of boost. What pulley combo will get me there? Have a 2 and 4lb lower ring. Is the accufab tb a restriction? Should I upgrade from my Bosch 105 injectors? Motor is a teksid block, all arp hardware, 98 cobra cams, 9.5:1 compression and on E85 all the time.
