Hondata

I have a 2008 Honda Civic Si (FG2) with a stock K20Z3. My current mods are:

* Hybrid Racing Cold Air Intake
* Skunk2 MegaPower RR cat-back exhaust
* Stock exhaust header and catalytic converter
* Hondata FlashPro

I’m looking for a safe, reliable tune (or basemap) for this setup.

I am currently using one of their provided base maps that is labeled CAI,skunk2 catback and headers.

Though I am still on stock headers.
Thank you

Post the calibration file you are running with a log, and I can take a look at how it's running.
