i ran an fmu for 3 years and did fine but on borrowed time. get a 255 lph pump at least then get with scotty. i tell you now, you started out at the tip of the berg and all you need is to get scotty to tune and chip the ecu after starting out with some blue top 450cc injectors from a dsm talon or eclipse and a peak and hold box from an older civic,integra to start. but you can get wilder on an ls but i think scotty tunned a 246 hp stock ls and lots more with this stuff. trust me GET WITH SCOTT!
