Just replaced valve train, headers, long pipe, and high flow CATS. Check engine is not on and no codes are being thrown. When running through emissions, OBD monitors are registering as not ready. I've driven the car for 2 weeks and ran through a Ford drive cycle I found on Google but no luck...

For the past 3 years I always have to return to stock mid pipe for inspection (Texas). I have a JLT CAI and SCT/Bama tune. Today I was driving around town to get the O2 sensors ready and I feel the car is faster down low with the stock mid. Other than the sound, should I bother putting back the...

So I have this Mustang and I've had it a few years and not long after I purchased it, i noticed that it backfired. Most of the backfiring occurs when you shift or any other time that you instantly get off of the gas pedal. There are a few things we think it could be: The timing, the mixture, or...

Hi, I'm looking at buying a used 2011-2012 Mustang GT possibly online. This would mean that I would possibly get a non-CA emissions approved vehicle. I know if it doesn't have the sticker it has to have at least 7500 miles on it for CA to consider it a used car. Once it's past that mark...
