Will a tuner replace an egr delete?
I am interested in buying the SCT SF3 Tuner. I noticed on the descriptions tab it states "Removes the Exhaust Gas Recirculation functions from normal engine operation." Does that mean if I install this tuner I don't need to do an EGR Delete?
If not, what does that mean?
I just talked to their tech support, and they said it does not replace the EGR Delete, but it stops about 90% of the effect.
So, that tells me that is would be a good idea to get the tuner now, to at least minimize the effect of the EGR valve, watch my gauges, and when my oil cooler starts to go, at that time replace the oil cooler & do the delete kit. (Unless I end up with an extra Stack of money & I can do it sooner).
Sound like a reasonable approach?
Need to monitor oil temp and coolant temp. Those are critical for the 6.0L owners! Also the ScanGuage can monitor FICM voltage, ICP pressure, Boost, etc. Nice tool for less than 200 bucks
Don't think I need the Scan Gauge 2, since I now have EOT, ECT, ExT, & Fuel Pressure gauges. The basic Scan Guage looks like it has nice fuel monitoring stats though. However, since my on-board computer monitors trip & instant MPG, the only thing that would really add is being able to monitor the actual cost, isn't it?
Anyone ever compare the accuracy of the stock monitor compared to one of these?
As long as you have gauges other than the stock "idiot light" style gauge, you would be ok to watch the eot/ect spread.
The scangauge2 is quite the tool for under 200 bucks, tough to beat the cost versus what it can monitor that you can't any other way (beyond a much more expensive system).
Here are just a few gauges the ScangaugeII can read. These are Xgauges, and need to be entered into the SGII. Very simple once you have done a couple.
FICM Vehicle Power (Volts) (Should be 12 Volts, should not drop below 10.25 for more than 60 seconds, or 9.0 for 4 seconds. TSB 09-24-03)
FICM Logic Power (Volts) (Should be 12 volts)
FICM Main Power (Volts) (Should be 47-48) Your FMP should never dip below 45. If it does, your FICM is toast and needs repaired or replaced.

Manifold Absolute Pressure (PSI) (BOOST)
MAP is a standard gauge - but this XGauge is actually better than the standard one. It has a larger range which was needed because the standard gauge tops out around 37 psi absolute (about 22 lbs of boost), which diesels have no problem doing. This one should read well beyond 22lbs of boost.
With a little tweaking you can adjust this to read boost as you said.
To do this, just plug in the MAP code - get a reading from it with the key in the on position but the engine off, then based on the reading changed the last 4 digits of the MTH to whatever corresponds to your reading on this table
14.0 -- FF74
14.1 -- FF73
14.2 -- FF72
14.3 -- FF71
14.4 -- FF70
14.5 -- FF6F
14.6 -- FF6E
14.7 -- FF6D
14.8 -- FF6C
14.9 -- FF6B
15.0 -- FF6A
So, for example if you got a reading of 14.5 PSI with key on engine off you'd change the MTH to 01220320FF6F and the reading should read 0.0 with key on engine off and would then show how many lbs of boost you were at when the vehicle is running.
