Given the vastly better numbers from a number of aftermarket tuners, at much lower prices, it's not hard to believe nobody on this forum has yet gone for the official Chevy upgrade.
On the other hand there are quite a number of people who absolutely do not want to give up their warranties, and this would give them a little more performance without doing so... so I keep hoping someone will.

It's worth it if you're under 36k miles, want to protect your warranty coverage and add a little power. I'm considering running it due to the quality of the intake set up, but I'll do a custom exhaust and wait to burn out the stock clutch before upgrading that piece.
Once I'm over 36k all bets are off!
.....it's not the size, it's how you drive it

I got the GM "turbo stage kit" installed yesterday. I haven't driven tooo much and haven't done any serious launches yet, but I can say it pulls noticably harder. I haven't driven any other tuned sonics so I can't compare, but I can say it sounds amazing and makes the car a little zippier. Oh, and I can hear my turbo now too. So that's cool!
15 ft/lbs isn't a lot, and it's not as much as most tunes (40ish?)...but a 10% increase is still significant!!

It is. They reflash it with the Stage calibration, no need to actually replace it. Now I want someone who has gotten the Stage calibration to read it out with EFILive and HPTuners so we can see what GM did compared to the stock calibrations...

Did you do all three parts for the kit: intake, exhaust & clutch?
.....it's not the size, it's how you drive it
Nope. I just did the exhaust. The 2015 comes with the upgraded clutch from factory, and the intake doesn't really do anything performance-wise. Not enough to justify the cost...yet.
I have noticed a weird sound though...it kinda sounds like tires squeeling but more airy...i had passengers actually ask if it was tires, but i know it isnt. I don't think it's my turbo. It only happens under heavy load though and the sound doesn't really change with rpm...just gets louder. I'm wondering if there is a tiny exhaust leak around a flange when they installed it?
Doesn't seem to hinder performance though, and my mpg is still great (36mpg on an RS!)

What software are you using? GM factory calibration. GM performance calibration, Trifecta, EFILive, HPTuners?
That should NOT kill an ECM, ever. Try reflashing it again. Sometimes the flash doesnt complete successfully and needs to flashed again so the checksums are correct.

I'm using trifecta only the check engine light comes on well it was last few times i tried it nothing was working might have been the battery in the end but for sure it wasn't originally a battery issue in acc the touch screen/dic turned on but in on mode they just turned off now nothing shows in any setting buy like i said it may be the battery...
