I switched from my Quadzilla race box to a Bullydog power pup with the outlook monitor today. First impressions,the egt,s are less(200-250 degrees)with the BD power pup set in the (90HP) performance mode than the quad box,very smooth so far and no codes. I really like the outlook monitor,its pretty slick. There is alot of info suppiled with the display. This diesel stuff gets a little addicting,this is my third HP box in less than 2 years time,needless to say the wifes not very impressed :-laf coobie
