Basemap tune problem

[edvin777]

Hi, for some reason I’m not getting any power from hondata flashpro base tunes, I install a prldown pipe, and then I tune my car with hondata base tune, but it didn’t do any difference, do you guys know why this is happening, I have been trying to find any information about this but I can find any, thank you 🙏

Are you measuring this on a dyno?
