Don't take another FTP test, that's very stressful on your body, and any good training plan applies stresses in measured doses. You'll be too fatigued to do the next workout properly. Trust the plan for now.
Yeah, but what's he supposed to use for power zones? Those plans usually call everything out as % of FTP. He's probably been using HR zones, so that could be a starter. When one uses HR for setting interval effort levels, one always goes too hard to start with and then gradually levels down to sustainable or more probably a little below because of the harder earlier effort. So a good approach is to take a wild guess at FTP. So if the interval calls for 95% FTP (SS interval), try to ride at a steady power will will give you 95% of your LTHR at the end, and that'll be ~95% FTP. An all-out 1' interval might be 180% FTP, so if one is doing a 1' interval, go as hard as you can, see your average power, and calculate from that, ignoring HR.
One could also simply substitute the CTS FTP test for any Z4 interval workout:

If he's going to do this training plan by power, there's his learning curve right there. That's what I did, started using power right in the middle of a year-long training plan.
