Sct3

2004 with 174k not studded. Just got an SCT3 tuned it with tow 1 it's an xtra 50hp what I'm wondering is the performance tune is an extra 150hp I've read forums where guys non studded have driven with out studs for years and never had a problem and I've heard the opposite also. I don't have a heavy foot but wondering if any body runs with tunes without studs. Thanks

First thing you should do is verify your fuel pressure under load as adding a tune will add more demand on the fuel system. The pressure needs to be checked at wide open hrottle while driving and should never be less than 45 PSI to prevent injector damage. It's also a good idea to have a permanent fuel pressure gauge so you can monitor the fuel pressure because the 6.0L will run on next to no fuel pressure and you can be damaging your injectors without knowing it. You should also have some gauges that read live data and an EGT probe to keep an eye on exhaust gas temperatures.
