GM performance parts Regal Stage Kit 2012-2013

[TRIFECTA]

I can do a dedicated thread. I completly agree with you on the chance of engine damage with a Trifecta tune. The question was asked that if you had a trifecta tune and you went to the GM tune would your warranty be regained. A tune will not void your warranty. A tune gives GM the ability to decline warranty repairs. ie. regal comes in with any non-GM tune and it has a broken axle, a heated seat that doesn't work and a bad radio, It will be covered under warranty, If not you need to A. find another dealer, or B. call GM customer assistance scenerio 2 .Regal comes in with a non-GM tune and a piston is blown apart. The dealer will identify the failed component, then is required to email a copy of calibrations to GM Powertrain for evaluations. If they find any non-GM calibrations in history they have the ability to decline paying for the repairs. I have seen this go both ways. 08 G8 L76 rod bearing failure, had aftermarket cals for speedo and emmissions (had gear swap and cats deleted) GM paid claim as these where not considered "power adders" HHR SS LNF detonated piston, had "power adder" calibrations, GM did not pay claim

The TRIFECTA calibration does not increment the flash counter at all. The CVN numbers per write and the checksums all remains factory, no matter how many times you write to it. They can check it as much as they want and will never find anything suspicious. In any case, it's not a good idea to let the dealer know you are tuned, and second, we always recommend flashing back to stock before a dealer visit as to not leave any room for doubt. Now, if you have a good relationship with your dealer, that's great too 🙂

Good Relationship with Dealer is key! I agree that flashing back to stock is ideal whenever you deal with service especially with how easy it is to do using trifecta tune software and cable.

If you are going to heavily modify your car and mess with bolt on components you are going to void your warranty on those systems. pay to play hobby.

The air intake is available without the tune, however the retail price is over $800! I got the intake installed, found that the "water shedding sock" that goes over the element was not with the kit, there is not an itemized parts list with the kit so GM is checking to see if it actually should be included. It was a simple install and took less than 10 minutes. It fits very well. Noise wise it is comparable to any other CAI. The road are wet so I only took a short drive. Looks like rain for at least another day. Soon as it dries up I will post my evaluation of the tune. Here's the installed pics

Thanks for posting all the info and pics. Can't wait to hear your review of the calibration.

I have two questions, if you don't mind me asking:

1. Does this new intake actually change where the air is drawn from? In other words, is the plastic tube that is under the fender and goes up to around the radiator area still used to supply air to this new filter box, or is the air coming from a different location now? Looks to me like the air is still coming from the same inlet tube, which I think is fine since the stock one looks pretty good.
2. I know you already installed it, but I'm wondering if the diameter of the inlet tube right at the point where the MAF sensor plugs in is different on this intake than the stock intake? That would shift the MAF sensor reading compared to the actual air flow (ratio of flow going over the wires compared to total flow would be different). If so, makes me wonder if they had to do that to stay within the working range of the sensor at max flow? And if that is an issue, how do the other 'tuners' get around the problem of a MAF sensor that saturates (maybe WOT can comment?).

It does look good 🙂

Yes it does!! I totally want it!

Ordered mine today!

called my dealership early this morning to ask about availability, they had no idea what i was talking about lol, said they'ed look into it and get back to me, they never did... might have to try another dealership

 

[trucklt1]

did you give them the part #? Tell them to check it on GlobalConnect or OEconnection. They probably haven't update their catalog, or whoever they use for their catalog hasn't updated on their end

It still pulls air through the tube under the factory air box. The intake is made from 3" tubing which should be a very similar inside diameter as the stock MAF housing. MAF tables are typically modified for the intake which has to do with MAF location in relation to bends and filter location as these both create turbulence around the MAF sensor.

Just called my dealership and they want $694.38 plus tax for the kit. Yikes! programming the tune would be $90 and install would be about $200 based on their estimate. Guess I need to order elsewhere and then have them install it.

i emailed the manager the Part # along with the link so he can read what its all about… still no response

I just wish they made this for 2011, can't find any that can tell me why it will not work with a 2011......

Ok, I finally got to go for a drive and here is my review. Compared to stock tune it pulls a little harder through the mid rpm range, not much if any difference in max power, the turbo seems to come in a little quicker and after viewing the calibrations it appears that only minor changes are made in the max boost tables in the mid rpm range which improves driveability where these cars always feel a little jerky. And some changes in the MAF table to account for the changes in the CAI, and some changes for the underboost/overboost diagnostics. With the CAI and GM tune it is not as responsive in the mid range as it was with the Trifecta tune. The biggest difference I notice is that before if I was cruising around 40 mph in 6th gear and wanted to accelerate I would have to downshift, now it will actually pull reasonably well. I believe that has to do with the CAI ability to flow better at low air mass. The CAI is by far the best looking available, it fits great, easy to install. The tune and CAI give the car a little more pep and noise, but after having the Trifecta tune, the GM tune leaves a little to be desired. GM advertises the kit as a 20 hp increase (7%) on the GS and a 50 hp increase (23%) on the regal T, so if you are upgrading a regal T from stock you should notice a huge performance increase. This kit is 100% GM so there will never be any questions of warranty issues. Make sure you have your dealer "I route" your repair order for proper warranty documentation if you decide to get this kit. One other point I would like to make is that it has been stated that the Trifecta tune is hidden in the ecm and from what I saw when I checked my calibration ids and CVNs with the trifecta tune installed appears to be true. let me know if anyone has any questions

Thanks for the update

 

[cozbyrt]

Thanks trucklt1!

 

[dmenn]

With the CAI installed, do you hear the turbo any louder within the cabin?

Also, I recall on other cars with intakes I've had you can hear air sucking in when you blip the throttle.. do you get that with this one?

Thanks!

turbo sounds the same, you can hear the air sucking under light loads, not during idle, cruise or under boost. It is noticeable in the car but not so loud that it is annoying.

I really hope that this extends to the Verano T soon! Shouldn't be too complicated considering it's the same 2.0L engine.

I think the '11 Tubo's are all Russelsheim cars, right? The ECM may be different since it was shared with the Opel.
