Common FAQ:
Q: Will my vehicle throw codes or CEL with your calibrations installed?
A: If your vehicle throws codes with your factory calibration for an emissions-related item, it will throw codes with ours as well.
Q: Will my downpipes/catch can/air filter/etc. cause a code or check engine light (CEL)?
A: If any modification triggers emissions-related codes or a check engine light with the factory tune, it will throw the same emissions-related codes/light with ours as well.
Q: If I install an EGR delete, or other emissions removal parts, will my truck run correctly with your calibration?
A: We have not tested this and do not have an answer for you – we will not sell you our calibrations as such.
