At ECT above 144 or below 135 it seems to roar to life as it did with stock injectors. Even warmer and cooler ECTs (above 146F or below 133F) are much more forgiving of AFR at startup. You have to take a ton of fuel out to get any reaction in these ranges.
I just happened to come across this post whilst searching.
This is very similar to my issue with injectors going lean and happened at 49C to 55C. Your temps are around 56C-63C
Scott, could you check your logs to see if the injectors were leaning out at these temps?

Thanks
