Car will be getting a steigmeir ported Eaton next month. Pretty stock now has a k&n intake, off road h pipe, deatsch werks dual 340s, stock pulleys. Will use either a 2.9 or 2.76 with stock lower. I'll be happy with 450whp just want the blower to scream a little more. Should I upgrade injectors or maf also or will they be good for this setup?
