turning up my cat3406e

There's a fuel temp wire and boost wire package on ebay for 179 bucks seller is diesel freak. The fuel temp will advance ur timing boost will add fuel comes with knob to put in cab. Both are super easy to put on pretty much plug and play. Search for cat power harness and you'll see it. I have same motor that you have, mine was even turned up to 550 buy after this it runs perfect. Our ecms advance timing at over 150deg. Fuel will show ecm that fuel is 156. I set my boost nob on 3 thats my sweet spot

 

You can make your own fuel temp and boost wire. You just need to go to your nearest radio shack and pick up some resistors. What engine serial number do you have??

 

Might need to hook it up, have it put on the dyno, make sure its running correct before you start playing with tuning it.
You say it does not feel like its putting out 475hp find out before you try to fix it without knowing what the real problem is..

 

Another Flea bay sucker. $35 would have got both. And you need to do a little more reading to understand what you have posted is false info from the freak.
