Cam Upgraded required custom tune, but my ECU now cannot "ready" the EGR drive cycle...

[Drfy1]

Ive done multiple searches, so far ive come up with: return to original back up, drive car and "ready" all your drive cycles, pass your smog-check then install custom tune back. BUT my prob is the car wont run steady enough with the upgraded cam on original back up. Im definitely not putting stock cam back in and all. Is there a way to write a tune that doesnt alter certain parameteres enough so as to allow my ECU to proceed to "ready" my (non existing)EGR drive cycle? Any info or options is much appreciated.
Thanks,
