changes for slp MAF
The Effective are has to do with the IAC motor....if you changed to a different IAC motor..then you would need to change it..otherwise.leave effective area alone...
make sure you drill a hole in the 90m TB as your car needs teh hole to idle properly(same size that was on your stock TB at a minimum)
you are not going to get enough air through the IAC with your mods
