But tell me more about fake dynos and drivability.

200 bucks and I'll make you a fake dyno chart so you can brag and get some street cred at the next car meet.

Maybe this will help: https://www.dictionary.com/browse/drivability

How is drivability even in question with an engine on stock injectors and stock cam(s)? I've had other tuned vehicles with a large cam and bigger injectors and still drive very close to OEM, never even came close to having a drivability issue on an engine with stock injectors and stock cam(s) before.

It's not. The person who owns the car is on the forum, and he appears to be happy.

I think it's in poor taste to claim a tuner is lying or his tune not as refined as another - without proof.

One example: If the tuner is using throttle for boost control instead of properly adjusted PID to hit boost target, then it can result in excessive timing corrections and reduced power.

Another example: If the car is not properly load tuned but just running boost target then a car tuned during summer might crash the fuel pump during winter when the air density increases.

A third: Badly adjusted PID control might also result in drive train errors due to excessive charge pressure on tip-in or post shift.

None of these are hardware related but tune related, so yes, who you chose as a tuner is probably the most critical descision in your build.
