The L5P ECM lock: Is it worth the hassle to tune it?

[TorqueLab]

I’ve got a 2018 L5P and I’m hitting a wall with tuning. Since the ECM is encrypted, you either have to ship it out or buy a new unlocked one. For you guys who have unlocked it, is the power jump really that noticeable, or is the stock 445hp/910lb-ft already enough?

The L5P stock calibration is aggressive. If you daily drive, don't bother unlocking. But if you tow heavy, TCU tuning is way more beneficial than engine power.
