Ok, stupid question. I can see the possible damage that might happen if you cap the rail and it keeps hitting the roof. Something has to give somewhere.
I can understand that if it is capped and it keeps the rail pressurized, you will keep the fuel in the rail compared to draining back through the relief valve when you are in a WOT situation.
But, my truck is basically still stock (2005) except with RokkTech Sensor to advance timing, slightly better airflow (not aftermarket), RokkTech muffler and a somewhat heavy right foot now and then. Would this benefit me since I really don't have a guage to see what my current fuel pressure is when going down the road or even WOT? Would I feel it with my SOPG (seat of pants gauge)?
102,000 miles on truck so I don't really want to blow the thing up but always looking for a better performance mod if possible. Yes, some day I would like to purchase Smarty and all the guages that I currently don't have, but in the mean time. As long as it wouldn't blow it up upon first WOT, should I be fine?
How would I tell if something was starting to go bad due to this mod? Popping noise, damage to injectors, anything like that?
