Hey guy I upgraded some parts on my car for now but what should i upgrade next and my budget is around 500 bucks. I upgraded to CAI and i also got little turbine charger in the CAI =)) because it was just laying around.. I also got a performance chip X2 installed on the air intake sensor and upgraded to iridium spark plugs. I am pretty sure the car is well over 200HP by now.. hopefully.. So what should i upgrade next in that budget? I do not want to upgrade my exhaust because i do not like loud mufflers. I am surprised how fast a 1.7l engine can be =) Lets make it faster without blowing it up =)
