Got my A pillar gauges installed this weekend and got the Scangauge mounted. Everything turned out very nice. I ended up going with the GlowShift gauges for Boost, EGT, Fuel PSI, and Trans Temp. Scangauge is set to monitor FICM, Volts, ECT, and EOT. Couldn't be happier with the end result.
Fuel PSI stays right around 60 at idle and at highway cruising speed. At WOT I will see about 3psi loss.
EOT/ECT Delta currently running at 6* - 8*
Don't mind that CEL, it is the EGR delete and i've got tunes coming this week to take care of that.
ScanGuage can only monitor what sensors are already in the truck and tied in to the factory computer. They do not offer an EGT probe that I am aware of. But I was able to buy the ScanGuage and the Quad pillar guages for less than I would have paid for the CTS with expandable EGT and Fuel PSI.
