I took last week off to get all the little things done that had to be done for my oldest daughters wedding . I had received the EJK from Dobeck and installed it last week . Everything was great except I had 1 concern , the connectors fit fine into my injectors but the piggy back connectors wouldn't go in far enough to snap in to the lock part on the oem connectors , so 1st I wrapped them with electrical tape , after I thought about it I called Chris at Dobeck and he told me some went out that didn't get shaved down for them to connect the way they should so he told me to file them down 10 thousands . It doesn't sound like much but man what a pain ! I started out with just a hand file for about an hour then switched to a gringing wheel in my cordless drill and then back to the file . Finally after about 2 hrs. I was able the get them connected right . I was ready to take everything a part and send it back . I can notice the difference no decel popping , more response , and the exhaust even sounds just a little different . So far I'm happy other then all the hassle to install .
