So my 03 MSP is leaning out under boost, I have a wideband AF gauge and it goes all the way lean (lowest the gauge will read is 10) when it is under boost or hard acceleration. I have not really done any diagnosis at all so far, was looking to see if anyone had this issue before I waste a bunch of time checking stuff. Fuel supply issue? Do I need an SSAFC? It runs perfectly other than the leaning out/lack of power under boost.
Any insight would be great, new to the car, have done a bunch of work to it so far and would like to get this last issue resolved.
Thanks.
