yo!

Just purchased a 2002 WRX with a Stage IV turbo. anyone have a stage IV? or know what kind of mileage it would get? I haven't revved to turbo RPM much, seems like I'm going through the tank rather quick, A/F gauge seems to be in the 'rich' territory quite often. Planning on configuring a map within the UTEC for this colder weather soon.

I'm learning with this stuff, coming from late 60's Chevy BB territory. Hoping the UTEC will allow me to adjust for the denser air...

thanks!

 

it will but rich is safer than lean. you need to watch EGTs when you lean it out

im running super rich and i get 270 miles a tank if i dont get on it

better tahn a 502 hehe
