I did find today ive never driven with such low injection time at 40-50 mph, probably a combination of the two changes. I upped my ignition and hope to have even better results tomorrow.
I hope to find stock intake cam vvt settings I can imitate

right the 4+ , 4+ is not changing cam spec in relationship to each other just related to crank so that would be harder to notice IMO . Just the Ex 4+ is changing overlap so that should see change . If you did something similar on intake side should be more noticeable . Does Toyota Have a VVT version of that engine , If memory is right there 3.0 straight six did (used in turbo supra's .
You might be able to hunt down some info online or from there repair manual .
