My Isspro EGT gauge has never let me down in 11 years now. You can't measure EGT with anything plug & play, you'll have to crawl under the truck and drill/tap the exhaust for the thermocouple and run a wire into the cab to a real gauge for EGT .

 

As Rich said, EGT is important when towing. I, like him, have a thermocouple in each manifold. I have a dual channel gauge so it only takes up one hole in the dash
2-Channel Dual EGT Digital DPG-SD Pyrometer Gauge + Probe Kit
My only complaint is that it reads a little low at ambient temps. It was reading 45 this morning before I started the truck. Air temps were almost 60. 15 degrees off isn't too bad I guess

I don't tow in quite as steep terrain as he does, but I think I may tow a little heavier. I try to keep EGTs below 1100, sometimes hit 1150 to keep the turbo up on a long pull, but I've never seen 1200.

Nuthin' wrong with OCD

 

I like those Isspro gauges. I think I will order up two EGT, fuel pressure, and trans temp.

 

More importantly than being able to maintain speed is being able to stop and drive down the road straight. I agree with the guys on making sure your drivetrain is in good order. To me being able to stop and not have to chase the steering wheel is more important than being the first one to the top of a hill. Being able to get to the bottom of a hill without sweating is much more important.

 

I had an Edge Insight CTS in another vehicle and loved it. After a while I completely ignored the dash gauges and scanned the Edge as it had all the information I needed (including corrected speed). Bonus was the ability to change inputs on-the-fly which was very helpful in diagnosing when the vehicle did not run right. Ability to read and clear codes is a nice feature as well.

One note with ad-on Issopro sending units (except for the pyro) is that they do not like heat. On the vehicle with the CTS, I originally had fuel and boost pressure sending units mounted to the motor. After they died a short life a couple times, I went to the local hydraulic shop and had some hoses made so that I could move the sensors over to the fender area where things were cooler. They lasted until I sold the truck, so I never got a clear picture of how much longer they lived in this configuration.


A 4" exhaust (or any other larger than OE diameter size) will require a supporting mod to the turbo for avoiding surge. Surge will kill the turbo. Do some homework as there are may ways to go which span from a different compressor wheel to complete turbo replacement. Basically, each path has its trade-off and cost benefit.

 

Those pass specs sound like Snoqualmie... or Manastash.

I use Torque Pro on my phone for the OBDII gauges while towing - then I can switch to FORScan Lite for troubleshooting. Electronics don't age well, and having a dedicated device for years to come will look very dated in a short order. A tablet or smart phone is rotated through inventory on a regular basis, so your gauges will keep up with the times - and likely work for many more years than a dedicated device.

I don't recommend against having an analog temp transmission gauge, but it's on the OBDII port and you'll end up with two.

 

Yes, snoqulamie pass. And I will probably be pulling over Steven's, washington, and manastash passes as well. I think I will go analog with two EGT guages and one fuel pressure. And try out the torque pro app.

 

I have the Isspro EV1 gauges. I don't know if they are even available for purchase anymore, but they are garbage. If you go Isspro be sure the are the EV2's.

 

Thanks for the heads up.

 

I like my Isspro guages, but they don't make them anymore. I would like one to replace my banks EGT guage so they match.

Speaking of which Rooster, I think they have EGT guages that have warning lights on them. A couple times on light grades I've accidentally let cruise take my EGT's out of my comfort zone (under 1200) and a flashing light would have prevented it.

Probably not an issue until you get tunes, but a thought.

 

Warning lights would nice. I ended up ordering some "Glow****" gauges. Two pyrometers, fuel pressure, and trans temp. I read enough decent reviews to give them a chance. I got the whole kit coming direct from glowshift. If or when they fail me I will upgrade to isspro or autometer. I dont like to do things twice but I need something quick. To go with the 4 guages I will run Torque Pro on my tablet.

It looks like my up pipes are leaking. I haven't pressure tested them or the intake system yet. But I figure I will go thru it all now and upgrade while I'm in there. So Bellowed up pipes, 4" straight exhaust, 6637 filter setup, wicked wheel, banks big head, new intercooler boots, any O rings and seals I come across.

What am I missing? Should I delete the exhaust flap while I'm in there? Any other mods. Thinking about a DP tuner once thats all done.

 

Hydra tuner is more universal. More options.

 

I will check that out. Thanks.

 

I got the torque pro app going and took it for a test drive. The only coolant temp guage I found on the app will not work. I loaded the superduty PIDs. The gauge reads negative. Stock coolant temp guage works fine. The boost gauge on the app seems to work decent. According to the app my typical driving style in this truck runs about 5-7 lbs of boost. I punched it up some hills by my place and got the boost guage up to 16 lbs and that seems to be the max for the truck.

 

The automatic transmission trucks do not have a coolant temperature sensor input to the PCM, whereas the manual transmission trucks (built after 2001, and rated at 275 HP) do have an extra engine coolant temperature sensor that feeds the PCM data.

Auto trans PCMs rely on engine oil temperature to make temperature related decisions.
