Next mod for ~$300?

[P7M8]

I just got an '05 XLT 6.0L PSD. From what I've found so far is I have a Sinister EGR Delete, Sinister Coolant Filter, and an MBRP Exhaust (dealer cut the pipe and put a Cat on it in order to be legal for resale) Also a ScanGaugeII.

What's next? I was thinking an SCT X3. Thoughts?

I'm new to this. What's the benefit?

Your injectors need to have more than 45 psi all the time or they will go poop. 62 ish is ideal. The gauge will keep an eye on this. The pyrometer is needed so you know what king of Exhaust Gas Temperatures you have. Once you tune the truck, it can get hot under a full throttle run you wanna make sure you don't see over 1200 for extended periods of time, and don't shut it off til it is at 350 or so.

pyrometer is for nwatching your egts( exaust gas tempture) too high of egts all the time will have negative effects on the motor fuel pressure gauge will let u no whem you are in the danger zone too low or too high fuel pressuer and its no good for your injectors ...i also recomend you to do the blue spring mod . it bumps you furl pressuer up to a healthy psi . look it up its easy to do ...this site will help you alot with your 6.0 it has for me ....also be aware of your ect eot delta ....anything over 15 and id be looking for a new oil cooler ....mabey not so much if u have a egr delete ..but good to keep in mind ...good luck

Thanks for the input. ScanGauge has an X-Gauge setting for Injection Control Pressure as well as Fuel Pressure. Won't that work?

Also, I read that the blue spring will show faster throttle response. Mine is pretty quick off the start. How can I tell if this has already been done without taking everything apart?

you will have to hook up a gauge for the fuel pressure its not something that the truck has the abilty to read . has to be an add on just like the egt probe. the easy way to see if u have the blue spring is to get a gauge . i just bought a billet fuel filter cap for the filter under the hood and hooked my gauge to it so i could see what i was at for psi then took it off till i get sopmething for in the cab hope this helps

The blue spring install is a 20-30min job..

1.Remove secondary fuel filter and drain fuel bowl ( on top of engine)
2.Remove Airfilter.
3.Remove IC pipe from drivers side.
I think there is 4 hex screws that hold a housing onto the fuel bowl, (where the filter sits in) Remove the top two and you should be able to pull the housing back and see if the spring is brown or blue. You might have to remove the fuel line that goes to the housing.

Edit: while pulling the housing back, be careful the spring might come out.

if your lookinf at an sct i recomend SCT livewire and get the egt probe with it then you have a tuner and gauges all in one i got mine from defuser for $589 with mount and probe plus you can buy custom tunes built to your needs for anywhere from $40-$80 depending on where you get them
