Tuning underway on my son's completely stock 2018 Camaro SS LT1 with Magnum DI TVS2650. Only mod on this car is the Magnum DI TVS2650 blower - running CA's (Chevron) 91 octane. Otherwise the car is stock right down to the factory paper air filter.
This is the best power pull so far, I doubt that there is any more this in stock setup, but it is a nice improvement over the TVS2300 (550 RWHP). Might try a bottle of Octane Booster to see what that will yield.
Have some work to finish in the mid-rpm range, but looking forward to some track testing!
