The shop said the tune may have compromised burps (related from their conversations with VAP), but that they were still there.
I added sports cats to the valvetronic exhaust with this trip, and the burp is enough to irritate my neighbors from blocks away.
So for me the "compromised" burps are entirely satisfactory. If work allows in the next few days I will try to get some video.

Video should start just before a couple of the modified burps.
The duration of burps does seem to be a bit shorter, and the burps seem to largely be gone when shifting at wide open throttle and high rpm.
Overall I remain pleased. I don't think I noticed they were shorter before because my car is louder than it was prior to the cats.

1. Your exhaust sounds evil! It's loud even at idle, significantly louder than a stock V8 SVR that I test drove
2. You have the V8, I have the V6s. Missed this on your sig line before so I don't think we can directly compare VAP tunes. I don't hear any upshift burps in your video but I think that the V8s don't do this even as stock. I hear sufficient crackles, bangs and pops on the overrun when keeping the revs up to keep anybody happy. To me they actually sound better than the stock "machine gun"-like pops that are overkill and annoying IMHO.

I think your car sounds awesome, like an F-type on steroids! I expect you will notice a step-wise improvement in your track times with the TCU tune, Stage 1 and Stage 2 tunes in the future.

I guess I'll have to wait and see if someone with the V6 + tunes can get VAP to write them one to maintain the upshifts burps successfully. Your Dad maybe??? :-)

Out of +50+ edited inside a TCU file, I might only be leaving something in range of 3-4 maps edited...

I went out today and ran into an Audi R8 (~2022 but couldn’t tell if he was a “Plus”). We pull up to a light and I compliment his exhaust (straight piped), tell him I’m putting out about 650hp and he tells me outside of the exhaust he’s also got a tune (about 650hp, too). I laugh and say, “so same power but you’re A LOT lighter…but let’s see what you’ve got”. We come around a bend (desolate, desert road in CO) and I drop it into 2nd, then hear him drop a gear, too. We both punch it. I shift to 3rd but hold the paddle to get back into auto and let the car do its thing. A few seconds in and I’m absolutely shocked that we’re neck and neck. At this essay point, my pull is so strong I’m actually starting to creep away from him. Did he botch a shift? Maybe. TCS kicked on in his car? Maybe, but he was also AWD. Regardless, the fact that my F-Type with $3k in mods left an R8 driver asking himself “what the hell just happened” really makes my day. Kudos to Chris and Stuart for putting out another amazing product…wouldn’t have matched this guy without it.

Stuart, considering that we seen many reports of differential failures with a stock tune, especially with V6S LSD differential, what are you doing to ensure that increasing rev limiter (which is also dictates launch rpm) will not make this problem worse? My understanding that more RPM means higher peak moments at the time of engagement. Are you also making first gear engagement slower to compensate?

I did the pulley and tune last week, and to be honest I wasn't totally blown away like I was expecting. I think I may have just overhyped myself due to how dramatic of a difference some people have described here. I don't doubt the numbers VAP is quoting though. I installed the transmission tune last night and took it for a test drive and the two of them together definitely made a difference though. It really pulls hard, and after you get on it, if you let off it's ready to slam you back in your seat right away when you put it on the floor.

It still does have the lag downshifting when you first floor it after cruising steady for a while, which has always annoyed me. Sometimes it takes over a second to do anything, and when I asked the dealer about it they said that's just how it is. Once the transmission is aware you're ready to have fun it seems to be pretty good about dropping a gear quickly though. My solution for that is to pull the shifter over into sport mode before I floor it so it's ready. That said, sport mode or not the VAP transmission tune feels really good when it's going through the gears. I definitely saw it hitting 7K before shifting too, which was cool.

Anyway, I don't have any numbers to post (I did order a Dragy today), but I figured I'd post for anyone on the fence, as a satisfied customer.

TIA - am interested in this thread....

Depends a lot on your goals. Safest bet is to do nothing...then it is a continuum of performance and risk trade-offs.

I have them all, and I am happy with the setup. I do not spend time worrying about warranty or repair costs...I just mod and enjoy the cars. If something breaks, I can always throw enough money/time/effort to fix it.

No issues in Dynamic mode, sport setting with paddle shifts, very fast and crisp with occasional burbles on up shifts, down shifts also fast (near perfect).

My issue is when in Dynamic mode, S setting allowing the car to shift itself, burbles more dramatic but seems like too much after the first gear or two. The shifts and burbles seem to take too long. Particularly around 75 MPH can be slow, too many burbles. Passing a truck earlier this week, the shift around 75 had several seconds of burbles, enough that I needed to let off the gas because it wouldn't shift. It makes me reluctant to push the car in this setting. I assume that the I can get a different tune. Just curious if my experience is unique. Not sure if I would need a new TCU or just a modified ECU tune.

Any thoughts?

Thanks!
