I just got an edge evo, and it runs great on level three, but if I try to do a custom tune it starts sucking alot of air and running really rich And looping idle, but all I changed was the tire size and gear ratio? Any help would be great..

 

Are you running 91 octane?

 

Yeah I am.. Is there anything else I need to adjust? It was so rich it was pouring black smoke out the exhaust and threw a code or tp sensor didn't match maf sensor?
