If you have the faintest appreciation for musclecars, then you know that most car buffs thought the grim reaper of performance had finally reared its ugly head when electronic fuel injection (EFI) was first introduced in the early ’80s. This was a legitimate concern because all of the EFI cars at that time were considerably EPA cautious with a focus on gas mileage and emissions. However, over the last 20 years things have changed, and that newfangled technology has now been integrated into the endless quest for more horsepower.
What was once viewed as a limitation now allows for greater flexibility in both tuning and maintaining streetability. This didn’t happen overnight, of course, but the lessons learned by aftermarket electronic engineers from the early Cross-Fire and Tuned Port Injection systems have brought us light years ahead with the venerable EFI LS1 small-block. The real question now is...just how potent are the musclecars of today?
