I removed all the "fins" from inside the air box as well as the charcoal pack from the top, then I smoothed everything out with a sanding drum. I only cut out part of the bottom instead of the whole thing like some people have done. I'm also running a K&N drop in filter.
REMOVE YOUR MASS AIR FLOW SENSOR BEFORE ATTEMPTING TO MODIFY YOUR AIR BOX, AND BE SURE TO THOROUGHLY CLEAN OUT ANY DEBRIS LEFT FROM THE SANDING PROCESS.
Also, you will have to reset ecm trouble codes if you unplug the maf for extended periods.

So I went out to run an errand and got this:
Stew
'13 sonic LTZ 1.4 6MT
139 g/s, 66* ambient
Mods:
Tuned with HPT
42 lb injectors
Ported intake manifold
Bypass mod
I could only watch so many things at once but I believe RPMs peaked around 6,000 and boost peaked around 20 psi, although those two things did not peak at the same time.

I am right at sea level, give or take a few feet. I'll be driving a little later today when the temps are warmer than that run last night. It's been in the upper 80's to low 90's the last few days, I don't know how much temperature matters but I'll find out.

So I'm out driving and am at a place where I can safely and legally accelerate WOT, such as a freeway on-ramp, yes that's where I was... And the Ultragauge RPM alarm comes on just as I'm trying to look 
What car needs the default alarm setting for RPM to be 4000? It doesn't always beep, must be due to the ultragauge refresh rate, at any rate I'll have to try again later after I adjust that alarm to something more reasonable like 6500.
Also, I don't think it matters for the MAF1 gauge, but I have my engine displacement set to the actual engine size of 1.36 liters, not 1.4 like Chevy advertises.

Mine UG is set to 1.36 also.
I don't have the time to make the list part of the thread lol. But it would def come in handy.

I went out on an errand and was able to confirm with an ambient temp of 82* I got the exact same 139 g/s right around 6000 rpm but then it fell off pretty rapidly after that since I didn't alter the factory torque demand settings up that high.
That is so close to 140 that I'm just gonna have to tweak my tune!

Sorry to go off topic, but the wife and I are flying to Tenn for a week. Haven't had a vacation in two years, and I've always wanted to see Tennessee.
What's the weather like there now? And is there any "can't miss" things we should check out. We are going to Nashville, Chattanooga, and Gatlinburg.

While in Chattanooga check out the aquarium it's awesome.
As far as gatlinburg there is Cade's cove. And lots of touristy things to do.

Don't bother with the aquarium in gatlinburg sucks compared to the Chattanooga one.
