RyanPSD, I was thinking that in the low twenties was about all I would see, but I just was not sure, duw to my egt's getting high pretty quick with the chip installed. I guess I just fugured that I would not see my temps go that high so quick only pulling 6000lbs. I would hate to see my tempes if I moved up in load though!!!! Thanks for the reply. Does anyone else have anything different to add? Colin
