question about my custom tunes
 

First I want to say is my custom tunes I ordered are wonderful. I got a few questions. First I ordered the whispering tune and it doesnt work to well. The rpms slow but its still pretty loud. Nothing like my old injectors. Is there any way I can switch with another tune without paying since it doesn't work?

Next I was towing my boat in the 65 tow tune. I had to gun it pulling out of an intersection and boy did it go! but my egts went up to like 15. Is that ok? Just driving normal though towing its great.

Also sometimes at idle it seems a little ruff but smoothes out is that normal also?

By the way I got a 7.3 with stage 2 single conversion inj. From rosewood.

Thanks a lot for you help.
