2.0T LTG Performance Mods

[Buschb]

No tune yet, ordered an ipf tune and waiting to hear from them or receive the tuner. Ive read that the larger ltg throttle bodies have increased response with no tune, but torque management really limits what can be done without one. Afr shouldnt be affected much since its not setting any dtcs.

right on

Im honestly not sure if they do adjustments with datalog, or just a mail order tune. If anything they are 3 hours away from me and I'll set up something in person if i do more than just basic bolt ons.

I think that's where I'm getting confused.
The aftermarket support is not the same as other cars

I'm not a fan of buying a new car that I didn't need, But that damn TourX was too sexy
So now we have Buick station wagon that I want to throw a downpipe on.

Scheesh

A downpipe alone won't do much, put the money towards a tune. You'll see a bigger gain in power and it will put a big smile on your face.

 

[Buschb]

A tune would be fine
An intake and turboback exhaust w/a nice tune would be nice

edit: I'm of the mind tune after any bolt on

If you buy the Trifecta elite tune when it becomes available, you get unlimited retunes anytime you add mods.

So now we have Buick station wagon that I want to throw a screw blower and 5.0L Aluminator on or maybe an LT5 and a 2.6L Eaton. Might as well add a Tesla motor and battery pack.
Seriously, I think the best long term plan is work with Trifecta on getting a nicely sorted engine tune and tranny tweak while not messing to much with what the GM engineers furnished for hardware.

I’m of the same mindset. I’ve been down the aftermarket road and things get too finicky for a daily driver. I’ve always had really good luck with TDI tunes that utilized OE components, so I’d want a mild tune that doesn’t max out what we have, but takes better advantage of it without a huge sacrifice of reliability.

 

[BoostedRegal2.0]

The Trifecta tune isn't mild, it really wakes up the car but it won't effect reliability. I've had their tune for 5 years/70,000 miles and nothing has broken in the drivetrain. To me it's perfect for daily driving but when I put the hammer down it just keeps pulling hard through the gear changes.

Differences in terminology. From the numbers I’ve seen it still seems fairly mild in my mind. Now if the tune put down over 400 WHP, that’s not so mild.

A tune adds additional stress on an engine, so I’d be careful making an argument that it will be just as reliable in the long term. Let’s talk at 200, even 300k miles as that’s how long I run my cars.

The LTG is pretty well tweeked by GM already. I doubt that anyone could squeeze much more out of the stock motor than what Trifecta has done. Their tune makes maximum boost so there isn't much more power available unless you add a bigger turbo and the supporting mods.

The LTG is built from the ground up to be a turbo motor. Tuning for maximum boost won't over stress this motor. I don't think the numbers tell the true story of their tune. The butt dyno certainly notices a big power gain.

YESSS

Well. Despite the opinions on to tune or change parts or not, the original post's title is ltg performance mods. I got my regal 2 months ago and immediately started looking for more power, because thats what i do. Supporting parts are necessary to take full advantage of more boost, so thats what i am trying to share with others. There are ltgs mods out there, they just need to be adapted from other models since these are newer regals and not fully supported yet. Hell, if the engine pops, its a very easy motor to rebuild, and with better parts at that point.

 

[papoman3]

new to the tune game.
What would it typically cost, assuming just the "tune only"? (if that's even possible)

$430 for the Trifecta tune on a stock Regal GS

I think you're preaching to the wrong crowd here. These guys seem to want a tune that's conservative/reliable and they don't want to change out parts for fear of voiding the warranty.

Everytime I mention a performance tune in other threads here the factory warranty always comes up. I'm always willing to try to squeeze more power from my cars and I know that means the possibility of breaking parts that GM won't cover, so the warranty doesn't even enter my mind.

I just don't feel there's enough aftermarket support for the LTG compared to previous versions of the Ecotec motor. ZZ Performance has a lot of mods for the previous versions in the earlier model Regals but they have nothing at all for the LTG. That's why I haven't attempted to mod my car any further than a tune, but I'm very interested in how far you can go with your car and maybe I'll do the same to mine someday.

 

[stoopid]

can you datalog and dial the tune in over email

BNR and Trifecta do datalogging tunes. You get a base tune to load, then datalog until it's dialed in from there. BNR got me 300hp/340tq in a '15 Regal T (LTG). No mods. Zero drivability issues and no engine problems in the 15,000 miles I ran the tune. I had my fair share of fun with it in those 15,000 miles.

YMMV.

 

[BoostedRegal2.0]

Here's the increase in hp/tq from the Trifecta tune for the LTG. The Regal turbo responds the same way as the GS does.

TRIFECTA presents a complete powertrain power delivery profile recalibration for the MY2014-2017 Buick Regal / Regal GS 2.0T LTG engine and corresponding 6T70 automatic transmission reprogramming. The TRIFECTA Performance Buick Regal 2.0T MY2014-2017 powertrain calibration is an easy to install software performance recalibration with an included flash loader device that will yield specific power increases of up to +82 ft-lbs and +61 WHP (Peak vs peak gains of up to +38 ft-lbs and +58 WHP) to a completely stock Buick Regal GS 2.0T MY2014.

 

[BoostedRegal2.0]

Here's the dyno sheet for the Trifecta tune on a stock 2014 Regal GS. You can see the motor keeps pulling harder higher in the RPM range and the stock tune loses power at that point.

Very cool, I'm going to keep my eye on this.

Sounds great
