Hey i installed my greddy type s with a flanged upper intercooler piping. im pretty sur ei have everything connected right and shit. But it cant be because when i drive it, in some gears it will not accelerate anymore and it will make a kinda horn honkling noise. My guess is somthing is bleeding...

I have my stock airbox in. And with that upper intercooler piping i could only get 1 of 3 screws that connect to the airbox in. My final guess about what is wrong is that that box needs to be completely screwed down because its not able to suck enough air through the air box? i dont know man. Could anybody help me out please?

Thanks in advance.
