I have a 01 Silverado 4.8l with truck norris cam, headers, cat delete, egr deleted, I used a mail order tune from Michigan motorsports and truck runs great but when you go from drive to park the idle seems to ramp to 1500 and slowly come back down, and the truck smells real rich at idle. I haven't pulled a log yet i just got my interface (odbxpro) and will be pulling logs, but here is a copy of my current tune. I have 30 years of plc programming experience but am new to automotive tuning, I think after research the problem may be base running airflow, but i cant find that exact table in tuner pro or universal patcher. Any help would be greatly appreciated. Thanks
