Boosting question
I'm not exactly what forum I should put this in..but here goes! (Yes, I did search but couldn't find anything close enough to my problem.) I have a 93 Evo and I have a HKS EBC installed, when the car hits 0 boost with the BC on the car jerks a little bit...and then when it gets passed .6 and up to .9 the car starts to jerk again. When I have the BC turned off it still does it but not nearly as much. I looked at the hoses and I can't see any leaks, I replaced old spark plugs with brand new Denso Iridium, new fuel filter...doesn't seem to help any! Any ideas?

I just looked at how the previous owner of the car has the vacuum lines setup...I don't think they are right. He has the little air filter almost halfway to the engine when they arent supposed to be more than 3.9 in from the EVC box..and that same line has no vacuum at all (it connects to the wastegate - is that normal?)

shouldn't be, on mine, the vac line that goes to the wastegate, comes off the closed side of my MBC, so until that ball pushes up and opens that side, i wouldn't see any pressure on the line....
