I just installed my quad xzt towing box. It runs great but my egt's are to high for me. 900@70 0-80 wot 1450-1500.

those numbers are alittle high i think. i have the zxt on my truck and i see 650-750 at 70. wot it can get pretty hot but not 1500. the hottest i ever saw was about 1450 at over 100 mph. i wouldn't jump to conclusions about something being wrong with the box cause every truck's alittle different. but call quad just to ask if they think it's faulty.

how long does it take to cool down to 300? mine takes about a minute to cool down to roughly 325-350 when i shut it down.
i did the tone ring mod on mine, which adds alittle pump timing, this would help in decreasing your egts.

Went for another drive. About 750-850 @70 on flat ground. hit about 1400 at about 90mph 0-80 about 1300-1350.only takes anout a minute to cool down for shut off 350 .

You can do the tone ring for free, you don't need to order anything

My Quad 100hp chip set at 60hp (the same as the XZT) sees 600 at 70mph.
Wide open/long haul, maybe 1200?

I haven't seen my EGTs go over 1200 degrees since installing the new turbo, except when I'm ******* it on hills. My cruising temps increased though with the larger turbo from 650 to 750 degrees at 75 mph. All temps reflecting the race version setting.

My 555 ran a lot cooler than this 600.

i have an xzt tow on my 05. what is the tone ring mod that was mentioned?

Extending the length of the dowl pin hole on the ring behind the harmonic balacer thus advancing the timing. It can also be accomplished by buying a new adjustable crankshaft position sensor from rokktech for $70.
