There is enough hysteresis (slop) in the programming to take up for the CAI. They make a great upgrade on these, and many other cars. Beware large air filters that wind up just sucking in hot air from under the hood. That's where they don't work. Also, many aftermarket CAIs are a solution in search of a problem. We did real engineering level testing on many CAIs for a Dodge Challenger SRT (6.4L), and found that the factory airbox was the best thing going for a bolt on car.

BTW, I take *everything* Scotty says with a grain of salt. As an engineer and a wrench turner with decades of experience, I just about throw my hands up when someone quotes him. Watching him work in his videos makes me glad I am not the mechanic who has to come in after him. BTW, Toyotas are not ALL that, either.
