Do you have exactly the same FTP in both areas?
If not, that is the most common issue leading to discrepancies.
Do you have exactly the same FTP in both areas?
Believe it’s a Wahoo thing / annoyance;
The only thing that comes to mind is that maybe you have the pedals paired to the headunit with one on bluetooth and the other on Ant?
Thanks for the ideas, I am going to try to reset everything, see if that helps
Feels like I just answered a similar question
There’s been lots of issues with the way Wahoo records power.

I had a similar issue - Yet another baffling data discrepancy (Bolt / TrainingPeaks)
And this - Average power higher than NP - why?
The issues all vary slightly but most seem to centre around the problem that the Wahoo has a tendency to record “-” instead of “0” when the power meter isn’t being used, which skews the numbers when entered into training programs.
Can you link to your ride on TR?
I think the OP’s question only refers to the difference between Kj on the unit and TR, nothing to do with the “calories” metric.
That wouldn’t impact kJ.
so here is a pic of the workout and my wahoo from todays ride. everything looks fine except for the KJ
Googled this and came across this thread - doesn’t seem like there’s an answer or a solution, but it is an issue that some other users have experienced
Except there’s also an average watts discrepancy - the Bolt shows 167, TR says 174.
174 for an hour matches up with 625kj (watts x hours x 3.6) - so I think your TR numbers are trustworthy.
But 167 for an hour doesn’t even match up with 472kj. That’s the very odd part.
I am also experiencing this. Wahoo recorded my ride today with 1726 kj. It was a 3 hour 15 minute ride with an average of 214 watts. 1726 kj seems low to me for that duration and intensity. TR calculated 2371 kj from the power data from Wahoo which seems closer to what I expected for a 3+ hour ride. If I use the rule of thumb that 1 hour at 200 watts is ~750 kj, the Wahoo number seems to be significantly low.
Recording from a Wahoo elemnt with assioma duo pedals.
I use 720kj but practically same same. Using 25% efficiency for convenience,
rough estimate = hours * 3600 (seconds/hour) * power
= 3.25 * 3600 * 214
it is an issue repeatedly reported for those using Wahoo.
And the beauty is starva just takes the value from the source for kjs and calories and doesn’t bother to calculate it like TR. So it throws off intervals.icu fitness metrics for outdoor rides.
I got a response from Wahoo that was suprisingly helpful and transparent.

Whoa thanks for passing this along, good to know!
Unfortunately, Wahoo have known about this literally for years and have been releasing new products in the meantime. They released a fix for some power issues with the Assiomas in June 2018 (see Original ELEMNT BOLT Firmware Updates – Wahoo Fitness Support). They have been getting continuous reports from Assioma owners since then but it’s still not working. If I were a betting man I wouldn’t bet on this getting fixed any time soon.
Lo and behold. Wahoo emailed me an update on this issue and they claim to have fixed it. I have not verified this, but was not expecting them to follow up.
This note is a follow-up to your support request. We want our customers to be happy with our products and support. We appreciate your patience while this issue was remedied. The ELEMNT / ELEMNT BOLT / ELEMNT ROAM firmware version 13127 was released to fix the issue you were experiencing.
