I hear quite a bit of lobe separation and duration in there, but I don't know the cam specs

Congrats, sounds great, your build is very similar to what I was planning. Unfortunately, I scrapped my planned purchase of a 2021 ZL1 A10 because of the T93 encrypted/locked un tuneable TCM. |

What did you plan to do with the '21 that you can't do with locked TCM - drag, road course?

Drag, Roll Andrew at Complete Street Performance figured out a way to program/Tune 2nd gear starts, change shift points and improve torque management which helps to optimize the application of increased horsepower through the 10L90 transmission to the wheels for better acceleration and Elapsed Times than if the TCM was locked and or untuneable. ie. If two 850 rwhp tuned 2019 ZL1's drag raced, the one with the tuned 10L90 transmission would probably beat the one that did not have the transmission tuned for 2nd gear start, shift points and torque management. |

But I assume the TCM in a '20 ZL1 is locked and inaccessible, or can Andrew help my car too?

I believe both my blower and TB remain stock, but I'll ask.

According to several reliable Tuning shops (Jannetty, Nickey, Race Proven Motorsports) 2020, 2021 ZL1's and SS Camaros have the T93 TCM which is encrypted/locked and prevents tuning the 10L90 and 10L80 transmissions. Also, HP Tuners has said it is very doubtful if they will ever support the T93 or spend the time, effort and money to crack/break the encryption. Therefore, I changed my mind about buying a 2021 ZL1. I want my car to have high rwhp and a modified transmission to complete the package and get the most out of it. |

HPE tells me that my blower and TB remain stock, so there's a bit more hp in those two, but only if I have a new tune flashed. I'm not immediately certain if anyone in Denver has tuned an LT4 much less a modified one but there probably is
