Some Help!!!!

[C.A.T.A.P]

Ok i need some help because there is just to much to choose from. I need to be tuned as well as some gauges. So far my speed has been built like a sleeper. It has been stripped of the mazda speed3 decal. I would love to keep it as a sleeper as well.
1)Things done to my speed 3 so far....
-turbo xs down pipe
-turbo xs test pipe
-fugita cold air intake
-front and rear hokins sway bar kit
-upgraded rear motor mount
2)Things that i have found to choose from.
