Nope, I don't believe he ever drove it. He's chimed in on this post already (Green94 5.0). He traded my GT40X for the TFS stuff because he was selling it. Jeff (can't remember his screen name on here) kept the TFS stage I cam in the car with the gt40X heads it put down close to 300HP N/A. The he added a S-trim and with only 8psi it made 397HP to the wheels. The TFS heads you bought I believe flow between the AFR 165's and AFR 185's. Maybe Rog can help.
