AFR's at idle

i don't know why people worry so much about the car out of boost...

the emphasis i was trying to make is you should focus on what the engine is telling you, not ignoring the sensors but the wideband figures are just a basis and not always to be used as a fine tuning instrument. even tuning in boost i don't always treat the wideband as if the figures i am seeing are factual, there are many reasons that a sensor can be giving you false readings.

but 1700 EGT while cruising? now that isn't normal.

y'all can do what you want, you can call it blind tuning or whatever. back in the day before widebands and standalones that is how people had to do it. the tools just help make sure adjustments are working properly, the best way to ensure that the car is accepting the changes accordingly is still by feel to how the engine reacts to those changes.

just like a dyno is a tool, they aren't always the best tool for making adjustments with. some dynos don't load to real world loading, causing your adjustments to be off as soon as you take it off the dyno and drive it on the road.
