New Pb.....but
I through 4 Codes, any Ideas what I need to do to fix them
1. P0103 Mass Air Flow (MAF) Sensor Circuit High Frequency -PCM
2. P0171 Fuel Trim System Lean -PCM
3. P0068 Throttle Body Airflow Performance -PCM
4. P1182 Supercharger Inlet Pressure Sensor Performance -PCM
Can anyone explain these to me in Lamens terms. And Help me out?
oh yeah. 13.23 is my new Personal best.

the low coolant light probly came on from the harsh launch tosing the coolant around in the bottle thus seting the sensor off saying it was low/empty becaue the coolant being sloshed around i had the same thing happen to me at the track it was outa the hole.

Sounds like your MAF is a bit messed up.
P171 means your computer has to add more than 20% extra fuel in Closed loop mode at some point, which usually means your MAF is reading lower than it should.
However P0103 means your MAF was reading over it's limit which is probably 10k or 11k, I know a lot of people have to up this limit with mods.
The last two or rational checks meaning your MAF, MAP, TPS, SCIP sensors are lining up right (they should in essence back each other up and if they are too far off you will get that error)
Do you have an intake of some sort or amybe a K&N filter (oiled). You need to data log your car's MAF, MAP, SCIP, TPS, RPM, LTFT, ect to get a better idea.
It could be tuning or it could be a bad maf, or maybe any other one of those sensors thats throwing off the mix. I only think MAF because the 0103 is MAF related exclusively and the P0171 is also MAF related in closed loop mode.

Nice run bro! To get rid of the P0103 and P0171 get the updated GM Stage kit reflash. The P0171 also can also be caused by simple **** like your dip stick not fully seated or and intake\vaccum leak after the MAF sensor.

i've had it for 19,000 miles. ive had the 171 before, but never the rest
