Stock 05 6.0 with SCT tuner

[DREW34]

hey yall iv got a 2005 stock 6.0 i just programmed it with the SCT performance tune that comes with the tuner is this thing going to blow my head gaskets??

How much cylinder pressure does your tune add ? If you arent a cowboy, a 60 hp and 100 ft. Lb. Tune with tranny shift points shouldn't hurt it, be careful towing, keep an eye on egt and tft's. I am not familiar with sct tune levels.

i aint sure how much cylinder pressure its pushing. i think the performance tune adds 130hp and 250ft lbs. i have a bully dog watchdog that gives me some gauges but not everything iv read that a fuel pressure gauge is good to have.

A tuner will not cause you to blow head gaskets.

However, what will cause your headgaskets to blow is when the oil cooler gets clogged, causing the coolant to flash boil and rupture the EGR Cooler. When the EGR cooler ruptures, it dumps coolant into the cylinders which increases cylinder, lifting your heads.

The first thing you need to do is get a monitoring solution, like an Edge Insight, scan gauge II, or Dashboss to monitor your Oil and Coolant Temps. They should never be more than about 10* apart. If they are, your oil cooler is getting clogged. You also want ot make sure your FICM volts are never less than 45, 48 is great. Adding a Fuel pressure gauge is important too, as low fuel pressure wil kill injectors, not cheap trust me

Here are some links you should read up on:

Bulletproofing the 6.0

Personally, I wouldn't tune the truck until you get a monitor on it and find out what condition your engine is in. If everything looks good, and you have taken some of the preventative measures, like upgraded fuel pressure sping and coolant filter, make a call to one of the many reputable tuners and get some custom tunes written for your truck. That will make it really come to life.

i also deleted the EGR through the programmer

This is a good thing. But, it does not eliminate the potential for the cooler to rupture. You need to physically remove the EGR cooler from the Engine (EGR Delete cost like $150). Can you see EOT and ECT with the Watchdog?

i can see the coolant temp. and im not sure about the oil temp i need to look at it but the coolant temp is usually running around 180 185

[TooMuch03]

Thats not a bad coolant temp, usually 190 is ideal, so your thermostat may be on its way out, but some trucks just run cool, mine is one of them I am guessing it can monitor Oil temp too, and maybe FICM voltage.

You were right that a fuel pressure gauge is important, especially if you tune the truck. A tuned truck demands more fuel, and if your pressure regulator is compromised, you may not get adequate pressure for the injectors, you want at least 45 psi at all times. 62-65 is ideal

i can monitor the battery voltage not the FICM

[DREW34]

if i can monitor my oil temp what should it be running at?
