Car seems to pull harder at 1/2 throttle than WOT

I have the same issue with my T2, oil blowing turbocharger and all.

Stock fuel system other than a walbro, gutted cats but stock dual exhaust and a custom 3 inch TID setup.

I hit about a 10.6 :1 air/fuel ratio at WOT which makes the car feel like it doesn't have anything to put out. But if I go 1/2 - 3/4 throttle it'll stay between a mid 11 and 12.3 :1 air/fuel ratio and I can feel the power.

I'm using an Innovate LM-1 with LC-1 gauge setup and analog out for my ECU to read an O2 signal so it can go into closed loop.

Anyway that you can get ahold of a wideband setup?

I'm thinking your having the same issue as I am with running too rich of mixture at WOT and it's killing the power. The oil blowing turbo isn't helping either haha.

My one thought would be that the carbon from the excessive oil burner might be harsh on the wide band sensor. Ill probably invest in one over the winter once i get work lined up in colorado.
