You're right, but you can change at what rpm the timing changes occur.
From the linked thread:
Power Level 1 on the Comp is the same as the EZ, on Power Levels 2-5 addition power is added via the wire tap onto the VP44 injection pump. If the pump wire is not attached with a Comp Levels 2-5 can be ran, but the power gain is not any higher than Level 1, the power will come in much earlier in the throttle but overall gain is the same.
