Spartan said I had high exhaust pressure, kinda worried

I was on the freeway today and goosed it go get around some traffic. Spartan came alive and told me my exhaust pressure was to high. Just wondering if I should be looking for any issues that may arise. Never heard this or any thing for the spartan before so any info would appreciated.

Mods
Spartan running 210. Exhaust warning at 70 psi and limit at 75 psi
Banks intake
Dpf and egr delete
CCV mod

is your dpf on still? if so take it off with that tuner, if you have a muffler take it off and clean/inspect, if you have a straight pipe, take sensors out, clean pipe and sensors

Check you old connector, is it dirty, rubbing. It sounds like the sensor wire is reading some resistance?? I am surprised that your Spartan is even looking at that sensor since you are deleted.

That's what I thought. There is nothing plugged in to them. I have them tapped off and zip tied up so they stay clean and out of the way. There are no codes and I have never had an issue before. I have been tuned and deleted for about 3 years now.

From what I am hearing I am being paranoid.

the high exhaust press is not from the removed dpf sensors it is referring to exhaust manifold press, or turbo drive press. also listed as ebp exhaust back pressure, too high is what causes blow up pipes or gaskets in the exhaust system before the turbo

That is not high. You want to try to keep it below 70psi actual. Spartan reads with barometric pressure added in. So if you want to keep it at 70psi or below and you are at sea level with a barometric pressure of 14.7. 70+14.7=84.7 is where you would want your alarm set. So where ever you live, add your barometric pressure in that area to 70psi and set your alarm there.

The limit on the other hand is only good for the analog gauge setup. All it does is tell the gauge where to max out at. It does not defuel or restrict anything to that point. It is just like the needle on your mph gauge. Your mph cluster only registers 100mph so that is as high as your mph needle will read on the gauge even though you may be upwards of 110 or 120mph. The reason for the limit is because you don't want your coolant temp on a 1800* gauge like you would your egt's and it wouldn't do you much good to have egt's reading on a 250* gauge like you would coolant or oil

Ok perfect thank you for the info. What is a safe psi level to be set at? I live in Seattle WA area, so almost sea level.

If you are close to sea level then you should be around 14.7 atmospheric pressure. I would just set my warning at 85
