Need help with DTC1514
Just installed a pro-charger on a C5 2001, and every time I hit the gas it throughs this code and the car states reduce engine power and runs like sheet until I reset the code. Is common on C5 with blowers? Should I delete the code with HP.
Thanks

P1514 is an airflow test table used to verify the operation of the driveby wire.
If you are using hptuner or ls1eidt you need to increase the airflow rate in the 1514 table so that it does not occur.
If using ls1edit you find it in the "engine diagnostic tab" under that go to test parameters.

All boosted cars..
The table is based off of an NA motor and looks at throttle position and MAF reading and checks the table to see if its within range.
When boosted you blowing a bunch more air past the blade at that given throttle angle, well out side of what it should be NA. So, it thinks the drive b y wire has gone haywire..hehe
