Just took my truck to the bank and threw the P0430 code. Its a cat inefficiency code. It wasn't a long drive and I was driving like an old lady. I'm running the Whipple Stage 1 tune with intake and intercooler but no other exhaust mods. I went ahead and cleared it with the Whipple Tomahawk Tuner and haven't driven it again yet. I'm assuming it will just come back. Trying to figure out if this is tune related and exactly what to do. I sent an email to Jeff at Whipple but it's the weekend so probably won't hear back until Monday at best. Anyone else with this experience
