Safe amount of tune b4 gauges needed ect?

[cumminsrocks]

Curious how much tune is acceptable b4 gauges ect are needed. I am new to the powerstroke thing and learning, so please give details if you will. My brothers boss decided to let me do deletes,SCT tuner,studs and stuff on his 04 Excursion. The tow/eco tune is impressive to me already as i am used to gutless powerstrokes lol. Sorry. I am just wondering can i step it up to the next level and still be ok? Is level 3 to much? When is a intake and exhaust necessary and like if it had boost and egt gauges, what are the go/no go temps and psi's. I would greatly appreciate someone sharing their knowledge with me, and special thanks

You should've put gauges or a monitor on before doing anything. Gotta know the engines health before adding any go fast goodies. Don't fool with an intake, you will get no gain and run the risk of dusting the turbo faster. Get an exhaust or at least a muffler and cat delete. Either will work fine.

There is a write-up on what to look for and how to fix it. That'll tell you every common and not so common item to look for.

EOT,Fuel psi, ECT, EGT, and boost if you don't have factory gauge, and TFT if you tow heavy.
