If you have a Trifecta tune and a Forge atmospheric blow off valve and are experiencing rough starts and rough idles, and maybe decreased fuel economy, please send an email to [email protected]. Make sure to include your VIN number and a brief message requesting the new ECP tune for the atmo valves. This does not affect any other cars, only cars that have a Forge atmospheric blow off valve installed AND are experiencing rough starts and rough idles. We found a problem with our ECP calculations at idle and have corrected them. You are unaffected if you do not have a forge blow off valve installed.
