Torqstorm systems run about $3K, but you'd also need to replace your EZ Fast EFI with a system set up for blow-through boost. Mustang360° put a Torqstorm system on a built 5.0L EFI engine and got a 50%+ increase in HP with 10 PSI of boost:

• Before: 407 horsepower at 6,200 rpm and 397 lb-ft of torque at 4,500 rpm
• After: 638 horsepower at 6,400 rpm and 545 lb-ft of torque at 5,600 rpm

That's increases of 231 HP (57%) and 148 lb-ft of torque (37%).

Your cam has left lift and duration, so you're unlikely to get to those levels but, as noted in the article, that's block-splitting territory - so keeping power levels down a bit is not a bad idea. Limiting it to lower boost levels would probably be a good idea for purposes of longevity.
