okay i just received 1600cc and 850cc injectors, primary and secondary fuel rails, fuel pump, fuel pressure regulator, and all the other little things needed. My car is equip with all the basics (intake, full exhaust, radiator, intercooler, and PowerFC) and I am currently running a base map for the mods i have.

My question is... Will I be able to switch my injector size on the power fc and baby it around, until i go single turbo?

I have all the stuff needed to do the upgrade.... I just wanted good advice on how i should go about treating my seven after the install.

I also have the greddy pulley set, so the air pump is getting removed.

I have the silicone vacuum hose kit as well. any suggestions on if i should simplify the system, or keep it how it is?

I am planning on ordering the gt500r kit from a-spec within 2 months, so im not going to have it tuned with the stock turbos.

Just shoot me some information and advice, it would be much appreciated. Thanks!

i would just get everything done at once... i believe (not 100% sure) but with that injector combo without a tune you will run really rich
