One thing I have noticed a lot of difference in is valve lash. When you tighten the lash up (decrease the gap amount), you make the valve open sooner and close later. This allows for more air to get in and out. By tightening them up, the turbo lights sooner because more air is being shoved out at a lower RPM. This gives you a ton more efficiency down low from what I have noticed because boost helps burn fuel, when there isn't enough air, fuel is burned inefficiently. Inefficient burn can be compromised for less power by letting off and getting back into an efficient burn ratio, but this is inefficient in itself because you might be starting to go up a hill and you will either have to go up it slowly or maintain speed by giving it more fuel that will burn rich but get the turbo spooling eventually. Why should you ever have to wait for that turbo? Running the valves tight help out a lot, but there is more to it that I want to know. The exhaust valve is what drives the turbo sooner if you run it tighter, but what does the intake valve have to do with anything? Do they work hand in hand? As in to get more air out the exhaust valve do you need to run a tighter intake to get more air in? Is there any benefit to running it looser? One issue with running them tighter is you can only go so tight before the valve and the piston contact, which is not something that is very appealing
Thankfully valves tend to loosen over time rather than tighten.
