Gotta 2005 EVO MR w./ turbo back exhaust..took of my BOV cuz it was causing problems...what would be a good next performance mod, and if i did it would it require a flash?

 

Depends on how much money you want to sink into your car. IT would be a good idea to get a boost gauge, manual boost controller. Getting a tune would be the cheapest option yet still yield some good power. The other more expensive option would be cams, fuel pump, head studs and then a custom reflash.
