Question upgrade ECU?

ok, so i'm lookin' to drop in a high flow fuel pump/feul rail, and a set of Agency power AP-GDA-160 modified injectors (740cc), i've been told that some modified injectors require an upgraded ECU, or "piggy back" which i don't have. the website i found the injectors on said nothing about needing an ECU.

does anyone know anything about the above mentioned injectors, will i need a new ECU, or just a tune?

Agency power/vivid racing is not generally recommended around here. You might want to do some searches for vivid and determine for yourself if you want to give them your money.

You wont need a new ecu, just a tune...

Do you have other mods that even require a fuel upgrade?

Not only that ^^^ thread, but if you search nasioc you'll find tons of reasons not to give them your money. Google "vivid racing sucks", you'll find people in other communities/forums with nearly identical problems.

I don't know what your power goals are, but you likely wont need new rails. Read the Unabomber's fuel faq (http://forums.nasioc.com/forums/showthread.php?t=533787). Regarding injectors... I've used Helix, Nismos, and am currently running Sards. PEs seem to be working well for many. I know some around here are using deatschwerks.com modded injectors, if you want to go the mod route.
