I have an 2006 Evo 9. While running through the gear it's cutting time and smells like fuel. i hooked up a computer and got codes back for EGR, Failed Waste gate and some code with fuel. The only mods done are air intake and turbo back exhaust with no cat. Will a waste gate and a tune take care of my problems or is it something more. Sorry if an of this sounds dumb it's just my first time with an import and forced induction
