Count me in as another satisfied customer. The initial dead spot/engine lug is basically gone on my 2015 base A8. Car feels much more nimble, predictable, and responsive.
Hard to describe, but it just feels better. Shocked that GM hasn't caught onto this and put into production.
I followed the battery disconnect method. Lost a few navigation radio pre-sets and had to re-index the windows to get the convertible top to work again. No big deal.
The install was a little bit tougher than 15 minutes since the lower driver side bolt was tough to access and remove.
Excellent and quick customer service by Mike. He recommended: Use a universal joint extension in between the socket and the ratchet. Before that, loosen the duct clamp, pull the duct away from the TB and bend/flex it to the opposite side of the screw you are trying to remove.

I would agree that the throttle body does help off idle behavior quite a bit. The place where I really feel it is driving up a steep ramp onto my lift. I would have to feed in uncomfortable amounts of throttle and slip the clutch too much before.
I also had it out on the track today and I can't say it helped but I can say it caused no issue.
Finally got mine and got it installed....shipped fast but took forever to get north of the border(thanks Canada post). Gorgeous piece and installed easily. Did the battery disconnect relearn and started right up. Yet to drive it because our weather sucks.....will chime in when I do so.
On install, I removed the the large duct that directs air from the hood vent....allowed much easier access the the 4 TB bolts.

Yes it has made a huge difference on my A8, eliminated the lag and searching for RPM feeling on deceleration. It has made my gas pedal feel completely linear now. Where my foot is on the pedal, is instantly where my throttle is. I am also much smoother on the track especially with downhill turn transitioning to uphill, just feels "right" now and throttle control is incredibly smooth. For me personally, more HP was not a concern, controlling it is what I was after and the Soler has solved all my problems with OEM TB
In all likelihood, 70-90% of the reports are A8 cars. Mine is an A8, and I can say for sure that the response when I step on the throttle is vastly improved.
Also- why would the automatic be any different from the manual? You're not swapping something that effects the transmission. Its the throttle response that changes. Doesn't matter what transmission is on the other end of the torque tube. Aside from the likelihood to stall the car when pulling away from a stop, nothing is different.
Many experience with a stick don't remember anyone seeing the benefit with an A8?
Need A8 input.
Thanks

Another +1 for A8.
Removed the annoying lug I was experiencing with just partial throttle.
I don't notice the TB as much in manual mode and shifting myself (keeping the revs up).
But very much can feel the benefit in automatic mode.

While I like the road results so far I can’t wait til this weekend when I try it on the autocross circuit. Looking forward to see how it works on launch and corner exits.

The Automatic transmission relies on Torque Calculations from the ECU to determine how and when to shift. The ECU uses airmass and volumetric efficiency to calculate torque. You change airflow characteristics for what the ECU uses to determine Torque Output and desired Torque Output, you change the value given to the TCM (Transmission Control Module). Manuals do not use any Torque values from the ECU as it is unnecessary. Additionally, the tunes for M7 vs A8 differ in the off idle areas for obvious reasons so a ported TB would have a slightly different driver perception on the A8 vs M7. Both gain improved throttle response for sure.

I highly recommend the Soler throttle body. It greatly improved the throttle response and engine braking of my M7 Stingray. Excellent customer service too!

Is all that going to do anything to change the throttle response? Sounds to me like it might change the shifting patterns and that's about it. (What rpm to shift at, and how smooth)

Yeah that's pretty much what I said. What is your question?
Just placed an order. Looking forward to trying this out! Sounds like a nice improvement.
I installed the Soler a couple of weeks ago, and have now logged about 1000 miles. Very satisfied, and can’t really add anything that hasn’t already been said. The majority of my driving is at “five tenths” or less of the cars potential, and this product makes that type of driving more fun, more satisfying. The car is more responsive. Like someone else posted, my car is louder at start up - with the NPP fuse pulled, it shakes the building on cold start (I don’t mind. )
Is anyone else getting a P0121 Throttle/pedal position sensor code?
I've had mine since April ish and started out great, but the CEL keeps going on and off either by itself after a few days or I clear it manually, same code every time. And if it sits for more than a couple days, on cold start up, super rough idle at 1krpm and black smoke comes out the exhaust. I tap the pedal and it'll smooth out and go back to normal.
I'm in Denver. It was a special grind for the high altitude, maybe it's too much? I've been stupid busy with work and haven't been able to take it out much until recently hence the late review/question.
^^^ no problem here either, with my M7. I found the Soler was a nice improvement, especially in the low speed and start from stop situations. While I found the Soler had some effect on throttle response, adding a throttle controller (I like Sprint Booster) really gives you the chance to tweak throttle response to your personal preference. I really like the combination.
