This is a pretty interesting article:

Talks a lot about when flat vs. skewed IFR tables are used, and why. Some parts are confusing, but overall, a good read!
p.s.. Last night I scaled my 33# (36) stock injectors up to my new 60s by just multiplying the stock table by 60/36. Fuel trims are much more reasonable now (+/- 5%) and seems to be running well. I'll be logging more data to see how it does as the week goes on, but figured I would share that approach!
