Description
The Tapout Purple Belt performance package provides everything you need to support flex fuel, up to approximately E47 blend. This is easy to achieve on the street, since it’s basically half 91/92/93/94 octane pump gas and half E85. The low pressure (LPFP) and high pressure (fuel cam) fuel system upgrades provide the extra fuel system capacity required to support E47 fuel. And the E47 fuel provides the octane necessary for higher boost and ignition timing tunes. This performance package will normally produce gains of 125 to 175 whp, giving you 550 to 600 peak whp with flex fuel on a DynoJet dyno, using SAE correction and smoothing = 5.
