Ok. My mods are in the sig. I will be having a Steggy IV put on in the next couple weeks (being polished now ) and i am hoping to reach 500 HP. Will be adding an Accufab TB/Plenum and re-tune. Do you guys think i will reach 500 without any additional mods on this crappy 91 Octane Cali gas? If not, what more will i need? Thanks for the input!
