Hi - I've got a 2021 M2C completely stock. I just want more bang-for-the buck-power and hoping for a noticeable change in powerband delivery (as I've read higher RPMs power/tq curve brings it similar to non-detuned S55.

I know there are better functionalities and capabilities with other systems and methods beyond piggyback devices. But I've got a 2021 and it's more complicated than the 2019/2020 models.

Literally, my main desire is more power and powerband, not e85 etc. If I choose that route and need a better ecu hack, I'll consider what's appropriate at that time.

Which of these two would you recommend based on 1) issues (limp mode, boost issues, etc) 2) quality of the tune parameters - around-town drivability to WOT peak powerband 3) price point.
- Carbahn: https://carbahnautoworks.com/product...f87-m2c-m2-cs/
- Dinantronics: https://www.dinancars.com/products/s...arts/D440-0149

Also, do these two devices seem to be the same? Details on both products aren't that descriptive on the website. Where can I learn more?

Will both of these systems allow me to unplug/revert back to original mapping when bringing in the car for service or warranty work?

FWIW I live in the Bay Area and can make a trip to Carbahn.

Thank you all!

1) no issues with either one
2) both quality products, carbahn being a flash tune, would probably have smoother power delivery than a piggyback (no personal experience, though)
3) Dinan

Personal opinion: If the price were not a factor, I'd go with carbhan, but it's not worth being triple the cost. If it was my car and I had to choose between these two option, I'd go with Dinan

I think he's referring to the carbahn stage 1 piggyback

Thank you - it looks like Carbahn has a piggy back available (which is the one I was referring to). Much discussion in the past compared using their flash.

In this case, Dinan would be the better option in every aspect. they'll both perform very similarly, offer you the same features but Dinan does it at a lower cost

The stock tune and the piggy back curve is so disappointing. Goes flat at 5500.
