So checking Livernois' website I noticed that the High Pressure Fuel Pump for the SHO's is now available. So I called them and spoke with Scott. He informed me that this fuel pump will run using pure E85 but will still not attain maximum horsepower possible. He advised they have added a severe Firestorm kit which with the High Pressure Fuel Pump will attain even more horsepower using E85. The cost for this severe Firestorm kit is an additional $1000. So to those who have purchased the High Pressure Fuel pump what results have you achieved as far as additional horsepower is concerned? Are you using straight E85 or a mixture of 91/93 octane and E85? Are any of you using the kit described by Scott? Thanks
