He shouldn't need more than the 2" TBI. That's equivelant to a 51mm EFI throttle body. Last time I checked the RamJet 502 was using a 48mm TB and had no problems

. TBI is almost always fuel limited. When you get to about 350hp that's when you wan a 2" TBI, at about 450 the largers might help, might not. I would consider the TBI upgrade a waste when he hasn't gotten the fuel traightened out yet.
