i just installed my skunk2 intake mainfold into a b18b. i'm having trouble . seams like it been bogging alot. the idel is horrable as well. i tried to make the best of it and adj it to make but only got about 3-400 rpm at idel. it bounces to 100 rpms ever few mins as well. i raise the fuel pressure to tried to get ride of the bogging . that helps alot but i still am not sure if i am doing this all right. do i have to advance or retard the timing gear ?
