Help, RPM DIPPING.
I would think that your ECU has caliberated itself to compinsate for the HKS a little bit. If I were you disconnect your ECU and connect it after 15 minutes and let it figure out the stock derverter valve is back in,
Its not that.^ its probably your Mass Air Sensor. Its probably not working right. I had it on my car for 3 weeks and then switched back to the stock one, but i still had the same problem as you. i just went to the dealership today and they said my MASS AIR SENSOR was faulty. Good thing its getting fixed under warrenty. Go to your dealership and have them check it out. hopefully your car is still stock. well good luck! let me know how it goes.

did u just bring it in or u made a appointment? i am thinking about doing it too, but i don't want to leave my car there, cause lotz of people state that their cars has been driven after they picked it up.
what do you mean? like they take your car out for a joy ride? Well im sure they gotta test the car out after working on it i guess. Write down your milage if u have to drop it off.
I would make sure 100% that everything is tight, or do a boost leak check if possible. If re-setting ur ecu doesnt work.
My car was doing the same thing when i had a small boost leak at one of the boots.
Have you thrown any codes yet?

i haven't throw any code yet, but i am gonna have a friend check it out, i have retighten everything twice. but i don't know maybe it could be the bottom IC pipe?,
and there is some people on the forum say that the service people will drive their car for joy ride, and when they get it back, it has like more than 5-6 miles on it, test drive don't need that much miles. there is few thread out there like this.

of course they are going to test it out, just take it to the dealer and tell them whats going on, they tell you whats wrong with it, unless they're trying to screw you. Good thing my dealership isn't like that.
