09 GT500 running lean with JLT 127mm CAI and 2.5 pulley

[Latinwrlord]

I only see an option for the 2.7 pulley with the JLT CAI. I keep having issues with the car running lean. Would an updated tune resolve this issue? I called one time and your customer service rep suggested to up the Mass air table to 15% that works till i get under full boost. Please advise.
