I'm thinking about doing this for my 997S, any comments? Experiences? here's the pricing I got:

Labor - install EVO air box $68.00
Labor - install GIAC stage 1 ECU flash download $85.00
EVO High Flow Air box $595.00
GIAC stage 1 ECU flash down load $1095.00

This is from Max RPM here in WA state. If anyone knows a better place to goto, please let me know!
