Then check the tech to see what the engine speed is, you'll want it about 750 to 900 RMP. Then thighten the two locking nut on each cable and then take it for a spin.
That should help and it don't cost aything.
If I understand what you are saying, you want him to adjust his throttle cable tension so that the engine never goes to its actual idle?
I'm going to guess that he is using a manual instead of an auto, because this happens in the SVX as well when you go manual.
I don't agree with what you are suggesting, but he can do whatever he wants.
I would suggest going with the ECUTune because it works much better with the manual transmissions than the stock computer does, has a more aggressive timing map, revised fuel tables, and an option to hook up a switch if you wish to run regular gas(or E85).
