i have and 06 evo IX mr (stock)and im new with this car i have money to play with need some help what should i do first, to increase performance

 

turbo back exhaust.

Tunes help a lot, but one you tune you have to keep re-tuning when you add new parts. If you learn to tune the ECU yourself it will save you a lot of money in the future and give you the power now.

I suggest these mods:
turbo back exhaust
manual boost controller
boost gauge
air filter
tune
