Pssht..You are way off base on this ASSumption like many other people
that assume :-)
Bruce has done wonders on the GN motor especially the adaptation of LS1
coils, custom chip tuning for bigger injectors, GN suspension, Syclone
ecm adaptation and many other projects. He is widely known on the
DYI-EFI site as well as the GNTTYPE, turbobuicks, t6p sites.
