I have a 2022 Camaro ZL1 1LE 6 speed. I took delivery in May 2022. I had the Callaway SC750 product installed in June 2022. I spent 4 track days at ThunderHill in September and had a great time. Found a dyno shop in December and did 12 runs, 3 in each of the run modes, SNOW/ICE, TOURING, SPORT and TRACK. The results were disappointing. Here is the EMAIL I sent to CALLAWAY. No response after 5 business days. All thoughts, opinions, experiences are welcome. Dyno graphs are available if needed.



Pete, Sheldon,
I took delivery of my SC750 equipped 2022 Camaro in July of 2022. I currently have 2500 miles on it with 4 track days at ThunderHill. I took the car to a dyno and race tuning shop to check out the HP and TQ numbers in the 4 driving modes, SNOW/ICE, TOURING, SPORT and TRACK. The stock car is rated at 650 HP which translates to 564 rear wheel HP with 12% drive train loss, I have a 6 speed manual tranny.
I have seen stock numbers on uTube from 530 HP to 562 HP. The best HP I saw was 585!!! SC750 with 12% loss translates to about 660 HP.



Can you guys provide some insight into these results? I have attached the four dyno results.


DYNAPACK 3000 was used to make the measurements. The hood was closed. The measured AFR was 12 at the exhaust pipe. The engine temperature was 200 degrees before the 13 runs and stayed at 200 degrees after all the runs. I don't know if the intercooler temperature can be measured.



I have ordered a 2023 Camaro ZL1 1LE with A10 transmission. I was planning on putting in a SC750. However, these plans are on hold until I can get some explanation. I will wait until I hear back from you before I publish my results on uTube. Thank you for your support.

Depending on temps outside and if ur car was warm when they run it, 580s-600 is pretty normal for most places 720 packages. I'm going to guess your torque was in the 625-640 range?



That being said, lingenfelter and Callaway are knows to have shit (aka VERY conservative) tunes.

Callaway sucks.
