6.4 high egt's w/ h&s, 4x4, and tire sensor
Ive got 3 questions...maybe you can help...?
I finally make it to remote road near my house and want to see what the truck will do from a boosted launch with the hot damn tune. Build boost to about 5 psi and take off ....and the mini starts beeping at around 70 mph. Check it and looks like im defueling because pyro 1 temp. reached 1450. This was what the mini was pre set to when it arrived. I have stock exhuast with dpf/cat delete & s&b intake.
1) Is it normal for temps to get this high? How accurate is the reading on the H&S mini because the tire size adjustment is no where in the ballpark according to my gps?
Go to engage 4x4 and Im hearing morse code light clicking sound through driver side a/c vent, even louder while holding brakes -maybe vac. line is loose that activates 4x4?
2) Any suggestion on what and where to check?
Out of the blue on my way home from Houston to Ft Worth-I get dash light saying tire sensor fault. I just had new 35's put on about 2 months ago...I know i have plenty of air pressure...Just dont wanna spend half a day of my time replacing dpf and intake to make it look stock.
3)Anyway to isolate the problem on which sensor is bad?
Thanks in Advance~
