Parallel Fuel Mod - After Mapping?
 

The MY98 WRX I own is already mapped, but I never got chance to do the parallel fuel mod before Andy did his work.

Is it worth the effort to do this while I have the manifold off?

Cheers,

Wayne.

IMO, it's definately worth doing.

Should even the fuel flow out across all 4 cylinders, and reduce the possibility of any detonation occuring.
