OEM tune with LPE twin pump
I have a question for the experts that I need some help with. I have a LPE twin pump in my car and engine blows so I bring it to GM to have a new OEM L99 installed with full factory warranty. MY cost :( Will the LPE show up when they install and check tune? Throw any codes or any issues with OEM stock ecm? I know it will work just trying to find out will it show up and or cause any issues with tune and warranty.. thanks for any help!!

Maybe I 'm asking the question wrong. With a completely stock L99 and ECM if you install a LPE Twin fuel pump will you have to adjust tune any or will the stock ECM not even know it's there?
thanks for any help or thoughts on this

My Livernois twin runs with the stock FPCM settings, don't see why yours wouldn't.
If the tune has been altered at all they will know though. Even if reflashed to stock.
