at a loss as to why my car now shows ways too rich on my NGK/Powerdex. I run your 5.7 Alky chip made for 26 Lbs with a JB 6265..Idle was just as you said it would at 13.2 warm and WOT at 11.2, like you said it would..car went 125..high tens. Last winter i upgraded to -8 feed and -6 return and a stronger,DW350IL pump,,old pump was fine but getting old and i upgraded. The issue> I just bought a Bison 6766JB turbo and bolted it on with no other changes but fuel line and pump ,adjusted f/p back down to 43. First blast showed 26 Lbs ..and did feel lazy, .. a glance at WB showed 9.4 ..plugs look rich too. How can this be with a 90Lb/mn verses 70Lb/mn turbo..why wasnt it very lean?. I cant verify WOT f/p as my gauge is junk and never reads even close othr than idle. I also did bolt on a spare F/P reg i have and it showed same W/B # at WOT 9.4. I dont feel comfortable just pulling fuel without an logical reason for this?
