Howell EFI & Engine rebuild & correct cam

I have a 1991 Grand Wagoneer in California with 112,000 miles. Recently had the engine rebuilt, with some mild upgrades. Also upgraded to Howell EFI. The chosen cam is a Comp Cam XE 262H. Duration at .050" intake 218 exhaust 224.

Everything is together, idle is smooth, but there is a low end hesitation and it stalls every once in awhile. We have checked grounds, the alternator has been upgraded, and check all vacuum connections. With many hours researching this forum, I have come to the conclusion that the camshaft is the issue, specifically the duration of the cam. Howell recommends below 210 and 220, and I have also read on this forum to stay below 208 and 215.

So short of removing the cam and installing a new cam with the lower duration, are there any other workarounds?

Thanks in advance for your input.

well thinking outside the box, what about creating a vacuum with an electric vacuum to a canister to the intake? may trick the computer into working better? might ry this with a race motor that was having issue during the norra race this year with the same issues?

How about increasing the fuel pressure?

That's not a bad idea either, just need to figure out how to fool the computer to make it work better
