i switched from a bulldog to a php and i noticed a difference in egt's.... dont quote me on this but i believe that phps tow tune is more of a true to towing, while bulldogs tow tune is just a lesser hp rating to try to keep egts in check.

 

Run nitrous constantly. Ever towed a fifth wheel at 130???

 

Thanks for the laughs and advice!! I just ordered a chip from PHP

Until then, I will make sure the wife has her track shoe with her when we pull the 5th wheel in case she needs to PUSH me up the big hills when the EGT's get to high!!!
