AED tuned a GT350 and got 493/426 to the rear wheels. Respectable and about what you see on those cars. They then added a CJ intake, throttle body, FRPP cold air intake, and injectors to the car. On E85 the car made 522/440. Torque really wasn't given up at all anywhere. It had 40 rwhp gains in some areas. Plus carried the HP much better. Peak power was 6975 with the stock intake and 7550 with the CJ intake.
This was all with stock headers, cats, and exhaust. That CJ intake has shown to be pretty impressive on the GT and GT350.
Could they get 550 whp with aftermarket headers and off road exhaust? Man, I would like to see what it would make.
