The stock injectors flow good up to about 600hp, so with a cam swap only that sounds like over doing it.
In general the VEC was a pain in the *** Piggy Back system, it's a Swedish system and our other Super Street Viper was a test Mule for it...did never work as expected.
There is a few systems out there that proclaim they work with the Viper, but most of them have errors, bad interfaces or have intermittent problem.
If I were you I would buy the new Infinity system from AEM when its available for the Gen2 Viper.
It's a $2-3K deal but it will help you.
Just find a experienced AEM turne with a Chassi Dyno, spend a half a day there and your Viper will Rock!
Btw, did you add headers when changing Cam Shaft?

Do you know of an ECM available that would replace the stock one? Most shops that claim they can supply one are very expensive with no assurances of success.
Thanks for responding.
