It clearly shows a gain... but I only need to look at it 3 seconds to know the ECU is up to its old tricks.

I know what a breather mod looks like and I know what ECU adjusted timing looks like. The gains shown here are ECU timing adjustments.

But there is more...

Note that the results are actually higher than with the TBS.

Do I think the TBS actually looses power? No, not at all. There isn't enough TBS to make any difference... Let alone lose power.

Its the damn ECU shifting variables all around. Notice within this set that there are two completely different sets of plots. Even though nothing on the car has changed.

This is classic behavior of the ECU.

And this is why I'm installing a MoTec!

And even if baseline dynod higher, its easy to see its only an artifact of the ECU. The stock ECU is messy.

Conclusion: The TBS does nothing up or down.
