There wasn't any problem going up but on the way down when letting off the throttle it lurched and he went into the tables and fixed it. It was going places he couldn't get to on the static dyno. Logging a actual run with all the turns and throttle/fuel changes should allow him to check for unexpected boundary conditions.

He did it by reviewing my logs from actual runs and then my driving the car while he watched the lap top. I really lucked out with this gentleman. He designed the hard ware for the Ford EEC1 in the seventies, he has owned his own software company, designed LSI integrated circuits and builds engines as a hobby he also tunes current EFI pro stockers. He has tuned literally thousands of cars and really knows the ins and outs of tuning. He really had no trouble building a 3D VE map that worked right away because of his knowledge and experience. I first talked with him when I bought a replacement wiring harness for the FAST XFI 2.0 unit. The cam on this thing is 287 at .050 on the intake and 293 at .050 ex with .818 valve lift so it is fairly nasty and now it drives very well at low speeds. I couldn't be happier with the results. He told me if I had a Holley I would not even need him to tune the system.
