Something else to check is the accuracy of the coolant temp sensor. This is easily overlooked and I'm one of those victims.

The sensor supplied from Holley is notoriously inaccurate.

One easy way to check is when engine is cold, after sitting a couple days, turn on the key and compare the inlet air temp reading to the coolant temp reading. They should be nearly the same within a degree or 2. If you see a 10-20 degrees spread, replace the coolant temp sensor.

When I first got the Sniper, I did 2 installs on our own cars here, and both of the temp sensors ended up reading high by about 15 degrees. This really skews the cold and hot start tables as the engine isn't really as warm as the Sniper thinks. Before I had realized it I had already been doing cold and hot start tuning and ended up with completely out of whack start tables to compensate for what was a faulty temp sensor.
After I replaced the temp sensors I obviously had to start from scratch and completely retune the start tables.
