Since the instilation if my trickflow intake manifold and e303 cam when I floor my car the car will pull good untill about 3500 rpms. After that point it will still pull but not as hard it does not sputter but it just feels like it is starving for fuel. When I drive my car on the freeway for about 15 miles and then get off and floor it on the surface streets it pulls like a monster untill about 5500 rpms. Why the difference in the pulling or power. I also have a 65mm bbk throttle body. When I had my stock intake and stock cam with the throttle body I had no power loss. My cars exhaust also has a strong gasoline smell now. How do you know when you need a fuel pressure regulator or new fuel pump.. What else could cause this problem ..
Thanks
