    Question 2019 C7 Corvette Z06 tune needed

    Hi all, I'm trying to see what (if any changes) were made to the fuel system calibration. I'm curious since I read the 2019 C7 ZR1 and 2019 C7 Z06 had a low side fuel pump added that has a higher fuel volume. So, if anyone has a stock tune for that year it would be really helpful. I checked the HP Tuners repository but there aren't any. Any help is appreciated. Thanks.

    Just took a quick look and it appears there was no calibration difference between the two in low side fuel pump areas. Do you also have a tune file for a 2019 Z06 (automatic preferably)? The ZR1 tune gives me confidence but I prefer to be thorough. I'm trying to figure out if the 2019+ low side fuel pump which is used in the 2019 MY C7 Z06 and ZR1 requires a calibration difference or if I can just stick it in my car with no calibration changes. It's supposed to flow 20% more volume according to comments by Tadge Juechter.

    It does flow 20% more. You'll run out of low side at the same time you run out of high side which is not a bad thing.

    Here's my 2019 A8 stock tune. As we know the TCM does not read without being unlocked my HPT.
