It's all in the tuning. A lot of tuners will just tune WOT and not bother tuning each VTC table on both VTEC tables, not to mention part throttle. Customers also don't want to pay for good tuning either. Could have also been due to a sensor failure. I grenaded an engine because the O2 sensor failed.
Normal car, you just tune one table for WOT.
For the K-series, you have to tune 12 (VTC 0°, 10°, 20°, 30°, 40°, 50° for both non-VTEC and VTEC). That's just for WOT because at WOT the ECU is in openloop.
Tuning part throttle closed loop tables takes longer, but the tables are interpolated and you can use averaging to speed up the process.
Tuning 0° VTC is important because that's what the OEM ECU (with K-pro) will use if you throw a code and are restricted to limp mode.
Hondata has a recommended process on their site if memory serves.
EDIT
Yes, they still have it up. From my post on SF
