What these tunes run, not your numbers: heads, injectors, converter, fuel and altitude all change what your engine wants. For starting values built for your engine, injectors and fuel, use the turn-on tune builder. A turn-on tune only gets it running: always finish on a dyno, and read our safe tuning limits before any wide-open pass.
Installing it? Follow our LS cam swap guide (Gen III and Gen IV, any chassis), with every torque spec you need. In a 1998–2002 Camaro or Firebird, the F-body cam and valve spring swap goes bolt by bolt.
