gm stage 1
ok so i searched but didnt see a thread on this and if there is link me to it and ill delete this one.
Anyway i was thinking about getting GM stage 1 because it keeps my warrany and adds a little more power. Yes i know everyone is going to say aftermarket is the better way to go but i need to keep my warranty. Basically im asking if you can tell a little bit of a power gain and was it worht the money.
Also any dealerships in MD install it right ive heard some messed up the install or something?

Way better than stock. Boosts to 20-21 psi and does not fall on it's face when switching gears @ 5500 RPM anymore. Gas mileage goes up a bit too.
Should have been this way stock. Well worth the money if you want no fear with the GM warranty.
Only drawback is you MUST use 91 octane fuel. Small price to pay.

Youre going to get obnoxious responses, like the one above, that are not necessary. Dont worry about it.

Thats a link to my thread about GMS1 and my dyno results before and after.
In short, yes there is a noticable difference. The change in power is huge, the care will pull insanely harder. Definitely makes for a quick DD.

Feels alloy stronger. Better driving characteristics in regular driving as well. I'm happy with and would do it again! Obviously aftermarket tune is night and day with gms1 but stock to gms1 is night and day too!

I use that now but i ts just because I don't mind paying the extra$3 just incase but I never thought you had to because the turbo is exit and doent deal with compression in the engine or atleast that's how someone explained it to me and they said I could run 87 in it with no problem

You're not to far from Sykesville, MD. I would recommend that you use Jeff Barnes Chevrolet to install the GMS1 kit.
They installed mine and I have had zero issues with it since the install back in Jan.
Ask for the Service Writer "Chris" and he will take car of you. My dealing with them has always been great and they have no problems installing the kit if you by it from outside vendor like CED.
Their attention to detail is great too. When I had my rear brakes done under warranty in May they also adjusted the tire pressures in all 4 tires to account for the increase in pressure due to the warmer weather. It's little things like that really make you say wow, these guys really car about my car.

The price was $249.95 to have the kit installed. I made the appointment with them in advance to have it installed and told them it would be a wait job. I got there around 1 and was out the door around 3:00. Getting updates all the time from Chris while I sat in the waiting area.

the best intake for the GMS1 is still AEM and K&N that won't skew your trims as bad. Your LTFT will be with 1-2% off. I have the revised AEM on mine and hasn't gave me any trouble at all. If you get the GMS1 make sure they are solder the wires to prevent LIMP mode from occuring because the kit doesn't like dynamic current on the sensors, just static.
