05 Duramax LLY Tuner?

I have an 05 Duramax LLY put air intake and exhaust on it. Now have annoying check engine light, when this light is on truck is sluggish. Maybe EGR?? Any ideas on tuners?
Any ideas would help.

Try and check for codes, might be setting maf codes and de rating the engine power.
