I have a 1996 Chevrolet Silverado with the 5.7L V8. I have added Edelbrock ceramic shorty headers, magnaflow true dual exhaust system, a K&N air intake, and a hypertech programmer (not the max energy). I know all these add power and provide dyno proven results but how much wheel horsepower have I really added? fyi...stock the engine puts out 255 and I'm not sure if that's to the wheels. thanks
