pulling as in sled pulling or towing? if you are towing you definitely dont want the tune dirty like that as your EGT's will be very high. what were the EGT's during that video? getting past 1600 degrees or so im guessing. i would say some of the fuel needs to be pulled from the tune or he needs to go with a bigger turbo so more of that wasted fuel is burned.

i know this is kind of an old thread but i was reading through and wanted to say something about it. not trying to be rude with my post just trying to understand more of what you are getting at.
