1. Post in the right forum. The 2.5L forum isn't the catch-all for all your questions.
2. Quit complaining about lack of power/boost when you haven't followed Cobb's path for success. Their path says: Stage 2 = full 2" TBE. You don't have one, so you won't see the full power. That's YOUR fault, NOT theirs. Research twice, purchase once.
3. Kwetching about a CEL without giving us the PXXXX code does no one any good. If we know it was a P0419 code for example, we could help. Not posting the code does nothing for anyone.
