Just installed 2 msd 6a's and two blaster 2 coils. I fired her up and now im running less vacumn, and the car runs like ****. This is only hooked up on the leading, im running factory trialing. I took the car for a spin after checking the vacumn hoses. When applying a boost(not wot) the car would studder. The car also wasnt going anywhere while I could her the wastegate. Could there be leaking air threw the throttle body and greddy elbow??? Is there anything that I need to do with Haltech e6k?? The only thing that was a good change is my guages(boy do they light up like there supposed too). Why are they lighting up better?? any help will be appreciated ..
