mike89lx,

The first step is to run a scan to determine the error codes that are causing the check-engine light to come on. I would certainly consider getting an FMU. The FMU will increase the fuel pressure under boost to maintain the pressure across the injector at a set value. If the fuel pressure is not increased under boost, the effective fuel pressure is reduced by the boost pressure (if the fuel pressure is set to 40 psi under no boost, the effective pressure will be 30 psi at 10 psi of boost). Why would the passenger side be lean and the driver side rich? I don’t know at this time. We are working on a similar problem here with a blown engine. Be very careful – The motor blew the lean side head gasket. If we get any more information on this problem we will certainly post it.
