is locking the timing bad for a daily driver? or should i leave the spout in?

Why would you want to?Half of history is hiding the past. -
heard from a couple people that it improves low end throttle response and idle smoothness.. was just wondering?ازدهار رأسه برعشيتComment

If you lock it in with low timing it will run like shit when you get into any kind of rpm. If you lock it in high it will run like shit on the bottom end. For a race car no big deal to lock in full timing becuse it is all or nothing. With a street car not a good idea. These people are jack asses.Half of history is hiding the past.Comment

i knew it was a good track day free mod.. i was just wondering about daily driving and wanted some imput.
so your thinking along the same lines as me, drive to the track with the spout in, lock it at 32 or around there and put it back in before i go home?ازدهار رأسه برعشيتComment

Advancing timing promotes low end torque, retarded timing promotes top end power - same reason they have "high speed retards" etc.
Removing the spout is not a good idea.
You will have to sacrifice performance with the spout out in two places, There will most likely be a range above and below where THAT particular timing setting "works".
Most cars benifit, ~10HP or so, with running the timing 12-16* with the spout out. Obviously, reinstalling it after timing's set.
Racecars, typically, don't get driven on the street and don't need flexible timing, so they lock them out.
generally speaking street cars, see high load - low RPM, they see low load - low RPM, and just about everything in between, the same reason there are different timing tables in the ECU and the same reason those tables are tuned according to load, rpm, baro, and air flow.Comment
