I put a TPiS intake modded for a 90mm TB and a LS7 TB on my CTS-V with a LS6 and am getting Reduced Power Mode when ever I get on it. Does anyone know what is causing this and how to fix?

Thanks, Jeff

You need to raise the P1514/P0068 Error table to match your WOT airflow (in g/cyl)

Thanks Russ, do you know where that is in HP tuners and aproximately how much?

Engine Diag>General>TPS Sensor>Cal Airflow-P1514/P0068 Error.

Start by multiplying the entire table by 1.25. Then do a WOT scan logging Dynamic Cyl Air (g/cyl). Just make the P1514/P0068 table values slightly higher then your scan values.

Thanks Russ, found the table and have increased by 1.25. I am gonna install the tune and see what happens. Really appreciate the help!

Well, did something bad. Went to flash and was having trouble connecting so i tried to write full pcu in test write mode. It connected but was going to take 15 minutes so I unplugged. Now car shows low battery error and won't turn over or even try.

That was a major no-no. You probably just killed your PCM.

Good luck.

Update: All is good.

Battery in car was bad and once replaced everything is fine. According to HPTuners support, they don't know of a way to ruin a PCM when in "In-Active Test Mode" like I was.

Also, made the flash today and it fixed my original issue.

Man I need to get hptuners. Or find someone around here that has it. My car needs some tuning too.

Yea, I just found a shop and did a dyno tune. I use HPtuners to import and mod the dyno tunes when I need. I can't tune cause I am a novice.
