Last month I installed a used Boss 302 manifold. I used the previous owner's injectors and fuel rails as his had less miles than mine. I also installed a new Steeda intake tube, JLT catch can and new spark plugs (NGK 6510). I had Lund tune the car. Interested to see new HP numbers, I had the car dyno'd at 2 different shops. Here's the second shops dyno graph: As you can see, I'm leaving 100+ horsepower somewhere. This just doesn't make sense. I'm not sure where to look. I emailed Lund but they haven't responded to my last email in a couple days.
