I guess it all depends on what he/she wants on his or her car..... More power to ya if you find a good tuner. I know all of my friends have alot of respect for me when I help them with there cars/trucks.

Also keep in mind if and when you upgrade the injectors, most good aftermarket fuel rails have a port for AN fittings and a pressure gauge. If you plan on doing more to the engine to get more power out of it later on, (HP can be addictive). If you wanted to increase your boost, but you never upgraded your entire fuel system to get the best performance out of your turbo. Your loss in the future.... I know you need to do alot to upgrade the system, but if your going to do somthing why not do it right? Voltage booster, High volume Pump, larger lines, AN fittings, High flow Filter, Pressure regulator, high volume rail, and aftermarket injectors. Total cost for a good system is around $600.00 after install and tuned. But most people dont have that much $ to spend on that, but if they ever wanted to do somthing else, like Nitros, turbo, supercharger, or just machine the crap out of the engine. Im not telling you what to do just giving you my experiences and info.
