look under stealth316.com Jeff gives some pretty good details on how to do it on his site. thats how i did mine, but i also did the battery move as well. basicly doing it the way he dos you get more continuous voltage to the pump, which is good.

There are diffentely benefit's to doing the hotwire mod with the stock fuel pump. From the factory you do not get the full 13-14 volts that is possible when the car is running to the fuel pump. With this lower voltage the fuel pump is not capable of pumping as much fuel causing you not to be able to get as much fuel to the engine. If your engine is stock also then your not going to notice any difference, but once you start modifying the car you are diffentely going to benefit from having more fuel avaliable.

I'd say no with the intake, exhaust and the iriduim plugs. however you might with the 14 psi, giving it a little more fuel with the extra air. don't get me wrong, i run denso iriduims but i don't realy consider them mods. personaly i consider intakes and exhaust as investments for future mods that will make a difference, but thats just me...

No. You probably aren't near fuel cut with those mods at that fuel pressure. You do a hotwire/rewire of the FP when you need more fuel. As you mod more, if you run into fuel cut as a result of the FP not giving you enough pressure, then you do this mod.

A hotwire would be overkill for you anyway assuming you have no fuel controller. I would do the rewire instead right now since you will most likely be modding in the future. It is all you need for stock injectors. I was running too rich with hotwire even with the LS6 MAF/MAFT. Now with the rewire it is perfect.
