the CTS-V does not have a dual pump. That's false. Completely false.

The CTS-V pump does have a higher flow rate buts its very minimal, maybe 5% I think .



The ppv would need to have the Fscm programmed to the ZL1 calibration to match the ZL1 flow rates, or you can just try to buy a zl1 FSCM but that would likely cost more.

black6 is correct, the 5th gen, caprice, and zl1 fuel pumps are the same but have a different calibration programed in the FSCM.

wow is that it?

why does lingenfelter call their $800 dual pump kit a upgrade if it has duel pumps stock ?


The way its rated I always assumed it was one pump

they are small volume(flow) pumps

the upgrade is to larger volume(flow) pumps , and they might wire their 2nd pump differently

I inquired about the lingenfelter dueal pumps but they didn't really want to share much info. I wanted to know what details needed to be edited in the fuel pressure control module to run the dual lingenfelter pumps but they wouldn't really help ?

It would of been the ideal setup for me possibly.

i like changing a single pump to a dual pump when there is forced induction or nitrous , you run 1 pump all the time , and use a hoobs switch to boost reference the 2nd pump to come on , and with nitrous the 2nd pump wired with the solenoids to come one when activated

im not really that familiar with the dual ctsv setup
