Just bought a nice low milage 2001 ho 6sp 410s. I do not plan on doing any mods nor do I plan on towing anything, have always wanted this truck and will use primarily as sunday driver. I have ordered a fuel press guage and a FASS lift pump which has been great in my 2002 work truck. If I do no mods is there a need for the pyro and boost, in other words could I do damage to a stock engine if I put my foot into it?
