I just finished a super charger install. When I got it back from the tuner it threw a 1514 code at just under 5,000 RPM. I should note the tuner did take the car well beyond during tuning. In addition to the 1514 it also threw C1278H,U1064H,U1016H& U0196H "reduced engine power" & "service traction control"

I returned it to the tuner and he made an adjustment in some density table and increased it to what I understand to be 80% above the stock level. On the way home same thing, just under 5,000. Just before I ran it up (while driving) it did have a radio code. Could the radio code be related to the 1514 or is it just coincidence? LS6 with A&A S/C running 13PSI.

Thanks

PO 1514 is a common code for any modded LS1---All you have to do is go to the "predicted airflow table"and add like 30% to the entire table-In EFILIVE it is table
C6101---not sure what it is in HP Tuners
It will never go into limp mode again !!!

I believe he maxed out that table. It was only happening during a third gear pull. 1,2, and 4 were no problem.

Thanks for the response.

If it is still going into limp mode it could be the TCS TQ limit---Stock is 350 Lbs with the TC button ON----Try turning the TC OFF and see if it happens then--If not then you would have to turn if off all the time you want to drive it racy----You can raise the TQ limit to the max of 640 but that would totally eliminate the TQ control all the time--The TC is your friend---It will save your *** when you aren't ready for max power like around a turn at WOT---
I asuume your car is a 6 speed---But as an example even a STOCK C5 when adding a large stall converter will multiply the TQ so much that it will exceed the stock limit of 350 lbs---- and the only way around that s to turn the TC off to get full power--and much safer !!!
