Short answer is yes. Check out the Tuning Forum for more information.
Yeah I understand what you are saying, its not a fixed amount of gain just because the car is tuned, the amount varies dependant on driver skill, the vehicle in question and the tune applied.And you're dealing with a wide range of driving skill sets in your competitions there. For instance, lets say driver A is a Seasonal top 10 driver and driver B is a top 500 driver. Driver A is going to make an average tune look good just because of his superior skill set, thus he is going to make more gains in lap times from a certain tune making it appear that it is the tune making most of the difference. What I am talking about with my post above is this: I, or anyone else, gives a certain driver a tune, if that driver is already at or very close to his limit, that tune is only going to help him out a certain amount....around .200-.400 that I posted above. There is no way that, if I am already close to my limit, that a tune from someone else is going to help me improve 1-2 seconds, no way. Do you follow me here in what I'm trying to say? I know I'm probably not making it very clear so let me know if you don't see what I'm trying to say.....its early here and I just woke up.
)I know you said you did, but I just wanted to further clarify myself. 
Yeah in the case of one tune vs. another you're not likely to see such massive gains, the recent FITT events have been split by less than a second between seasoned tuners and first timers. I also mistook your earlier statement for the difference between stock/mod and fully tunedI'm talking strictly about going from one tune to another such as in the case in the TT events. You will not gain 1-2 seconds in that instance. (unless the tuning involves weight reduction/power upgrades of course) If you are talking about going from the default settings when adding custom suspension, LSD, etc., then yes, of course you will get those types of gains. I'm talking about what I've experienced in TT's where I have a tune and then I try other tunes, I am not going to gain that amount of time (1-2 seconds) just from tweaking suspension parts. If that were to be the case, you would have to pick up that time straight away (first few laps) because anything much after that is just purely due to improvement through running the event. If you are talking about the same situation as I am, then I totally disagree with you. In my 5 years of doing time trial events, I have only seen this happen a very few times....more like the exception than the rule.
@DolHaus Do you see where I'm coming from with this? (Now that I'm more awake and can explain things better.

A decent basic tune will have no real discernible speed difference next to a highly ranked track specific tune under race conditions, its only in time trials where the difference will be noticeable 👍
That's simply not the case. They are in the top 10 because of their skill, not because of any tune. I really have to laugh when I see things like, "Wow, wish I could get ahold of his tune, it must be awesome" or statements along those lines. Sure, they might have a good tune, but nothing that's going to work miracles for anyone. Hell, a lot of the time those guys are using my average tunes with a few tweaks and we all know my tunes are nothing special. At any rate, those are the types of situations I'm talking about, no tune out there, vs a tune you are already using, is going to get you an improvement of 1-2 seconds straight away. You would have to have a really 🤬 tune for that to be the case.
Definitely true in regards to skill, I'm both an able tuner and driver and I still find myself looking at those guys on the top of the leaderboards and wondering how they found that extra second. It mostly comes down to skill in these cases, I might even be running a better tune but I just lack the talent to go as fast and no amount of fettling will ever bridge that gap.Good, good, glad to see we're on the same page here. 👍 I look at this question from a different point of view every time its asked just due to me being a tuner/time trailer and how I see the question as it relates to said events. (people trading tunes in the Seasonals)
To further follow up on this subject, I think there is a big misconception in those Seasonal threads that the top 10 (aliens) have some super tune(s) that they are using and if one can get ahold of such a tune, miracles will happen.

A really "bad" tune like replica can make a car "slower" than with highly optimized tune for TT ( same weight, power and tire ) I always consider there are 2 aspect, driver skill and the car potential. A skilled driver can bring a "slower" car to it's limits in lap time potential and beat a "quicker" car with average driver.
I think you missed the point.
It absolutely can and does. If I use a car for a TT and then use it for a TT with the same criteria at different track...it requires at minimum changes to the toe and diff, sometimes struts and rear ARB. Different tracks call for different setups to suit it's characteristics; ie Deep Forest versus Silverstone - contrasts like that. Could be the difference between toe in or out in the rear, softer struts, looser diff, etc. You may be exiting turns at lower speeds and need to compensate for getting out of turns with diff, gears, toe, camber, etc. at a lower speed track. Maybe it is a track on the cambered, bumpy side. Maybe it is a very high speed track where you don't have to worry about exiting turns at low speeds at all, etc., etc., etc. In every series I do and all of the other participants - we all change the setups track by track. Because...we'd be slower than what we could be running. It is in no way a different concept in TTs and I can't possibly see an explanation that makes it unnecessary otherwise.

I've only run a few TT's in GT6 but I'd say I agree with this wholeheartedly. I'd tune cars on my own, run 10-20 hot laps, then sometimes try other setups like yours or others, and most of the time, even if the tune had radically different settings than my own, my times were fairly close. Some of those wackadoodle setups from GT5, like 200 kgs ballast in a weight reduced NSX with negative toe did not suit me at all, but it didn't stop me from taking them to a decent finishing position. Some would say I didn't max out my potential but I did finish top 50 in the only TT I made an effort at in GT6 and probably tried 5 different tunes and they all got me to about the same point within 3-4 tenths. I found the same in GT5 as well.
