http://www.fiveomotorsport.com/oem-fuel-injectors-0280156013Ran with 1000ohm resistor inline with the coolant temp sensor for a small bump in additional fuel. 02 sensor kept a very nice 0.85vdc after 5k rpm making the most power. These cams I'd suggest more for Track DE's since the real power band is 4500-7000 rpm.
