Lex/560s wont go rich even with lots of fuelpressure and safc tweaks

Another thing to add to the pot. Your TPS only reading 70% is likely fine - I suspect that your SAFC is displaying throttle percentage based on a 5v scale, and all the Toyota TPS's I've checked are WOT at ~3.8v, not 5v.

Weird? It used to be 0 at idle, 100% at full throttle. Now its only 68% and has tps code. for a year it was 100% at wot, 0 at idle and was fine.....

Base fuel pressure is what your setting with the afpr. Spec is 33-40 psi. It will be rising rate so for every psi of boost the for will add 1 psi of fuel pressure.
