Fully tuned on ECUTek, vs bone stock baseline. I actually have a full step by step test (I put the test pipes & exhaust on first, then tuned; then put on intakes, and tuned again) of the parts. The exhaust mods pretty much made power using just my stock tuned calibration from before, minor changes.

When I put on the Stillen intakes they lost power pretty much EVERYWHERE, even after fixing the fueling. I had to get really in depth with the VVEL mapping and then I was able to extra power out of the car with them.
