I want to get the most out of my car, and nitrous is the cheapest way of doing so. My plan was to run a direct port 120hp shot on stock turbo or ptp clipped turbo. My question is how do you tune for it off the nitrous. I know the nitrous is tuned with the jets, but how do you tune off of it, since most people say not to use a map clamp? Is a return line better than the ptp fuel pressure regulator? Just adjust the pressure close to what you need and then lean it out with more boost? I have most of the bolt on's except a bigger intercooler, besides a fuel rail what else would i need to run that big of a shot?
