tbi 350 cam help?

just bought a stock short block and bolted on heads that were ported with bigger vaulves and stiffer springs. and then installed a huggins 442 lift cam shaft. And my old motor had more get up and go than the new one. So my question is how big of a camshaft can you go on a tbi 350 and still run the computer?

Camshafts for tbi say weather or not they will run with the computer or computer controlled engines to be exact , sounds a little to big for the computer.
