It sucks that it takes a ruining a warranty to fix the issue but they would have to prove it aswell. I've heard the 19s aren't as bad and my tuner got HP to write my vin into 19 software so he had more parameter controls.

This is what is Fixed now..

Slow start with no throttle letting clutch out getting car moving before adding throttle, no bog (this is pretty much the only way you could avoid bogging with factory tune or no TB or intake)
Slow starts with throttle, no bog (this is where I was having most issues) this was cleared up somewhat aswell with a TB and intake but issue came back..
Dumping the clutch dry surface with and with out launch control, no bog (this is where I was most upset at my car)
I could never leave the line with out the bog.

Basically now you can drive however you want I thought I did more harm to it driving how Al Oppenheimer said to I burnt the clutch many times trying to get Chevy 's launch perfect with there nannies..

Exactly! I feel like in protecting the drive train they are forcing us to ride the clutch really bad. The only way around it on mine is more revs and driving it like a noob

Thats what scares me. I LOVE the car but I don't love it from a dead stop. Ive tried many different ways to drive it and unless you are at a higher RPM then it just really has a hard time. I have had those couple of times that I did it just right and the car took off as it is supposed to but those were the exception for sure.

I already went to your friends page and am just debating on it now. Ill have to really think about it a while and drive it some more to make sure. I haven't driven it in a while.

Appreciate the effort and feedback. Glad I never took the plunge on a TB

Well, it’s good for me to know that the bog issue might come back. This way I am not pulling my hair out trying to figure out WTF was happening.

Is till believe the ported TB is not a total waste of money even if the bog partially returns. Better airflow will be beneficial for me down the line when I do long tubes and other mods.

Well, we gave it the old college try boys! Seems like GM won this one and the only way around it is to tune the car. ****ers !!! Hahahaha.

Curious, are you guys talking about this bog when attempting a 0-60 run? As in trying to extract the quickest 60ft? or are you talking about casual driving around town?

Interesting..I've never "launched" the car..I did do one all nannies off, tach it up a bit and dump the clutch thing...it laid down 2 tootsie rolls as I expected without any drama ...I'll admit there was a bit of a learning curve being smooth pulling away from a dead stop at first, but I don't give it a 2nd thought nowadays.

I'd be curious to drive an M6 that has this "tuned out" and see if it is siginfigantly noticeable.

Resetting the ECM for TB changes is a requirement extracted from the service manual when replacing stock by stock TB, let along replacing stock by modified TB.

To suggest that the difference the driver feels is related to the ECM reset or the placebo effect is completely unfounded. Many customers do not disconnect the battery at all, yet they realize the benefits, which is measurable.

Modified or Ported TB's are for those who do not wish to tune or those who want a better flowing TB regardless of tune. You do not have to choose one or the other, they both improve different components of the delays.

I think we all know this is a compounded (mechanical and electronic) problem.

Thanks,

I read Some dude has 600 miles on his Soler TB and it’s running strong still. I agree with Mike’s point. This issue is both mechanical and tune related. Having a physically better flowing TB can only be an advantage.

The ECU might still kick in with the torque management from time to time but i would expect the bog/hesitation won’t be as bad as stock because of the physical differences between the stock and ported TB.

At least that’s what my deductive/hopeful mind is telling me.

I can't say for sure without reverting back to stock.

It hasn't been "weird" for me, but the rough idle in the morning has returned.

I've been working up the courage to revert back (I'd hate to go through the learning phase again if I'm wrong).

I think I'll revert tonight and report findings tomorrow... Inquiring minds n'such.
I went back to the OEM TB, I disconnected the battery and followed the Soler TB relearn process with my OEM TB to rule out learning as a pro/con.

When I compare Soler vs OEM immediately after relearn:
Soler feels better no doubt.

When I compare Soler after 2-3 weeks to my now freshly relearned OEM TB:
The OEM TB feels better.

So I suspect the OEM TB still has some learning to do and will also degrade in driveability and settle over the next couple weeks.

The remaining question is:
In a couple weeks when the OEM TB is all settled in, will it be the same as the Soler TB after it was settled in? I'll post back in a couple weeks.

As for placebo effect, I don't think it is. I think the Soler TB has a mechanical advantage over the OEM TB. I just think the GM Software is eventually outsmarting them both.
I'm going to bet the Soler TB would do well with a tune. But I'm tuning this car.

I am still very new to my M6 ZL1, but it doesn't seem to have the get up and go I would expect from a stop. I am assuming this is the bog everybody is talking about? I don't like it either. If I mash the gas in 1st gear while launching, I want the car to instantly push my head back into the seat like my C7 did. The C7 with the M7 didn't have any bog, but it made a lot less power too. Frustrating as I will never tune any of my cars.

Also, keep in mind, that Automatics have added built-in delays for the transmission to shift, like when coming to a stop and then accelerating we get about .5 seconds of zero torque commanded by the ECM. Traction control also does similarly until it figures out and equalizes torque to each wheel. etc.
