60% over stock injectors are a serious upgrade designed for guys pushing the envelope on stock bottom ends or for guys with built engines who lean toward good driveability. With adequate turbocharging and fuel pump components, these injectors will supply enough fuel to crest the 800 RWHP mark.  They're a very popular upgrade to our twin turbo kits. This is the best balance for a 700-800RWHPtruck that still sees a lot of street duty.  A strong unit that still has good street manners.  We highly recommend using either a 10/12mm pump or Dual Fueler kit to supply these injectors. Significant tuning adjustments are necessary.
