Seems i read so many posts that say "untuned" in the tech section or in signatures. Since the advent of the 4.6 and especially the 03/04 cobra people throw the word tune around quite a bit. Not sure if they realize that the stock 5.0 computer system isn't all that restrictive, especially NA. Computers are far more restrictive on the newer cars, thus they need a dyno, as for we don't. Also, the cars with the most rwhp aren't always the fastest nor the safest. Tuning a 5.0 EFI car really just consists of setting the Fuel pressure and timing. Which should be done anyway after any real mods. The only way you get an abnormally high addition of hp from doing that is if you screwed it up to begin with. And by driving the car around "un-tuned" with a power adder, you are really risking a blown head gasket. So admitting that isn't all that smart. Not trying to bust people's balls, just realize, set you FP and timing and be done with it.
