i need help cuz i have a problem with stillen intake GEN3 .

after i instaled the intake the Acceleration of my car it be Worst than stock
my car is G37 sedan 2010 pleeez help me what can i do

 

I don't know anything about them but I will tell you, you need to give a LOT more information if you want help. This tells people nothing.

 

check that all hoses are connected and tight with no kinks in the tubes. also do a ecu reset. you will loose a little low end but more than make up for it top end.

 

evrethings are god and i check the hoses and tubes and i did the ecu reset
and i got nothing

 

make sure that the hoses going to black platic boxes are not pinched. also make sure that your maf sensors are installed correclty and not dirty. other than that you will need to decsribe in more detail what is going on during acceleration.

 

ECU reset takes 50 miles to relearn your driving style.

 

I would try resetting the ECU so you give a chance for your car to relearn with the new intake. Has the acceleration decreased THAT much?

How is your idle?

 

what purpose do the little rubber hoses going to the black boxes serve?? I have had my stillen intake installed for like 20k miles, I know for a fact that the clips that hold them in or so tight that they are breaking the rubber tubes because I have noticed cuts in the rubber tubing. How could I buy new replacement tubing, because it came with the kit, would just general black tubing of the same diameter work?
