autos in "manual mode" will stop at certain revs if you wanna rev higher thats what the "power mode" is for. My car is permantly in high boost and usually always in power mode
please make sure first thing u buy is an alarm many cars get stolen or at least attempt to steal them when they have no alarm.
My cars an auto too and please dont think the first thing you need to buy is a 'fmic' its not needed for your standard set up yet and its quite abit of hard work on the auto as you cant use the same pipework that manuals use.
Get your alarm, and then i'd suggest buying some braided brake lines and/or lowering your car. Autos in my opinion need a lil extra on the braking as your fighting the drive of the engine when you brake.
