If it's more indicitive of the tune then that's saying something about the stock NA engines and how much power might be available to them with a standalone.

I am using the 550cc injectors that came with the RE engine. But I dont really count injector size helping with power. Even the 460cc injectors will support enough Hp in n/a form, possibly make more power from the SMALLER injectors, but that is another subject. The fuel pump was upgraded to a msd/walbro style, the stock GSL-SE pump was "almost" there. I did install Series 5 n/a rotors. I would really like to have direct ignition that the FC has stock, as that alone would possibly net 5+ rwhp or more. But I built it on a very tight string budget, and got the old F10a haltech for $100. Its hard for me to plunk down $1k on this car for ignition control .

I know for a fact that a S5 n/a 6-port will not gain 50-60rwhp from a standalone install. I would love to think so, but its not possible. The AFM is not super restrictive, a loss of 5-10hp is pretty realistic. Tuning and timing will net another 10-20 or so. I would love for someone with a 6-port to prove me wrong, but they require so much work to get there. The 4 port of any type produces 180+rwhp with so little work. And its hard to make less than 170rwhp even with a stock exhaust mani, and 9.0:1 rotors. In my opinion the 6-port just cant do this.
