upgrade to TT injectors with your mods. Answer is no. In a TT, the injectors will support roughly the equivalent rwhp to cc rating of the injectors. The bsfc for an NA is less than for a turbo charged application. Meaning you can make more hp in an NA than a forced induction engine, given the same size injectors. Make sure you use a bsfc of .5 when you are figuring correct injector sizing (.5 for na, and .55 for forced induction). Additionally, some of your mods free up horsepower by lessening parasitic loss...that doesn't require additional fuel. From SZ, "with today's fuel the NA injectors will support about 250 rwhp".
