5/19/18 UPDATE AFTER MHD PUMP BEF: Editing this post because this needs to be said. A few hours ago I did the pump bef via mhd and all I have to say is: My. God. After a little driving and giving the car time to re adapt map 5 and dial everything in, I am in shock at the difference this made. Responsiveness, smoothness, faster spool + a couple more pounds of boost, and the car throws me even further into the back seat! If anyone ever is on the fence about doing a BEF, there is no reason to wait or debate it. The outcome is UNREAL! Couldnt be happier! |
So the jb4 is on map 5 as well as a back end jb4 flash? I'm currently on g4 and deciding if I should upgrade to g5 then mhd flash or ditch jb4 altogether and go mhd flash only. I guess the question is, does jb4 g5 + mhd make more power than jb4 g5 only or mhd only.
