I keep coming really close to ordering JB4 but i can't help but think a real ECU flash is the way to go for reliability reasons as long as the tuner knows what they are doing. I have a N26 so will have to spend a little extra on the ER downpipe which makes the downpipe + JB4 about $1150.
Has anyone used Mission or should i go with Enzo if they offer N26 tunes?
