thinking about getting an evo, but my concerns are getting some more power out of it and being able to sneak it through the dealership. so my thoughts were for basic bolt ons that wont void the warrany or things that can easily be removed like downpipe, exhaust, intake. but the real question is tuning. i have been looking at the cobb access port because you just plug it into the obd plug and if the car has to go in for work i can put all the factory settings back into the ecu. has anyone used the access port or recommend something else that can be easily removed without a trace. thanks
