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.
