Might possibly be the saddest thing I've ever read!

True, but his joy come this spring will be virtually unmeasurable.

Heh, it's like getting into an almost new car every spring. (Trying to look at the positives, you know )

I can not believe I did not see this thread before tonight. I read the first few pages & could not stop. I read all 48 & to say I’m excited is an understatement.

At first I thought to myself; “Hesitation? Not sure I follow.” Then I realized what was being discussed & yeah, it’s annoying. I always felt I had to give about 1/4 throttle from say & slow stop & go roll or going around a slow corner.

I coughed it up to a PCM function in pedal vs TB servo response only to now learn it is actually more a mechanical issue.

I’ll be ordering a TB & TC soon thanks to everyone who has shared their experiences & to Mike@Soler for what I can only describe as fantastic CS.

Unfortunately the death grip that is winters in Northern WI, coupled with my disdain of snow & road salt, driving it will have to wait until probably mid-April.

I got one and have nothing but praise! Added a rotofab cai and even better, so I finally pulled the trigger and bought a magnuson supercharger tvs2300. I seriously can't stop smiling when I drive the throttle response and linear power band is unbelievable! I seriously feel like if the pedal would go past the floorboard it would still pull!

New super fan here. Installed last week, and have 150 on the new TB. Followed the ECU relearn instructions to the letter. Amazing how a subtle change can have such a large impact on my enjoyment of this car. I love it. Shifts are smoother and mid-corner throttle modulations are heavenly. I do have a bit of surge as reported by others at around 2-2.5k rpm, but it has gotten better since the initial install. Only really felt in steady state throttle in that range, and even if it doesn’t get better I would not give up what I gained elsewhere.

So i read this entire thread. And have some comments and questions.

First of all, is the TB actually worth changing?

i ask this because those who have put these in have not really given any feedback that makes this sound like its really going to give you much gains. Rather, it smooths out the throttle. Which, for me. Isnt a problem on my stock TB. I would want to know performance gains. How much power are people gaining on these TB's? Has anyone hit the strip and got some data? Has anyone data logged after install in HPtuners? Has anyone had any tuning done for the TB?

Also, on the Soler Performance site it shows pictures of the throttle blade with no blade bar. And torx screws. Is this an updated design?

If there is data that shows that not only does the TB effect the response, but increases power i would definitely get one. Just seems to be a lot of holes in the 48 pages of this thread.

Regarding the surging, I have this issue on my car.

With a stock TB, Roto-Fab intake, and E85.

I believe this is related to the A8 shudder to be honest. And has nothing to do with the TB, or my Roto-Fab.

How would you see power increases of less than 10hp in hptuners data logs?

Thats not what i asked.

That was one of many questions.

Has anyone seen gains(on a dyno, or at a drag strip)

Has anyone done any datalogging.

And FYI, you can see gains in the torque in HP tuners. Before a roto-fab and E85. I logged around 440-460tq. After, i log around 490.

The MTB in my opinion is a QOL mod. Much reduced throttle lag is so nice.

Great question. The reason it improves the response in time and smoothness is by adding air/power at partial throttle, these are substantial enough that people can feel w/o the aid of any instruments.

The lower the throttle opening the more influence the throttle body has, at WOT the influence of the TB is minimal unless you make other modifications and the TB becomes the main restriction (bottleneck), then, modifying or increasing the size of the TB will be of some influence.

We ran a few tests recently on an inertia dyno, we were trying to get comprehensive data at all throttle positions to build a full picture of what's going on, but fell short due to the limitations of this type of dyno. We only got three data points of about 20 we were looking for, also the repeatability being much lower than we were hoping for. However, the numbers although limited and not accurate are indicative of what we were expecting.

Stock LT1 engine, Stock Tune, Soler LT1 TB is the only Mod;

At 30% TP OEM 21-28 HP, Soler 40-44 HP (~75% higher)
At 40% TP OEM 143-150 HP, Soler 173-182 HP (~21% higher)
.
. Missing data, not able to capture on inertia dyno
.
At 100% TP OEM 379 HP, Soler 384 HP (~1-2% higher)

We are certain of the behavior, not the magnitudes. Please understand that these numbers are not accurate (do not take these to the bank) and are only provided to give you an idea of what is going on.

For more accurate data, hold on for a month or so, we are in the process of compiling flow bench data, load dyno data, among other things to be able to publish and rightfully claim some numbers across all of our products.

I sent my stock tb this week to Soler to have them port it to help fix the surging I was feeling with my car mostly on low-mid rpm shifts. Primarily from 1st to 2nd and 2nd to 3rd. I got it back this morning and did the full ecm reset like they recommend. I can tell you after driving it about 50 miles today it was a huge improvement. I wouldn't say I noticed much gain in power if any, but the smoothness to me was worth it.

Get TC controller also

Thanks to all those that pushed us in the direction of the 3.6L V6 LGX Engine Throttle Body Modification. We are happy to announce that it is a reality today. Please see:
