I just installed a 20g turbo on my ej20 motor. I have supporting mods but just never had it tuned yet.
When I am just cruising the car spudders like once for a split second every like 3 mins. When it spudders it makes a squeeky noise for that split second. Also now I can't hear my BOV till I redline and it wasn't like that when I first installed it. I could hear it shifting at like 3 grand.
I don't know what is wrong with it. Could it be because of not being tuned, because I am starving of gas since I didn't upgrade the fuel pump or injectors. Any help would be really appreciated.
