Why should i take out my jb+ and sprint booster? Car feels much more alive with them, until i get a flash tune at least

I can bet you car is much faster with downpipe ONLY vs jb+ the way you have it now lol. I tested this a few months ago when my buddy (many not on forums) locally with X4 M40i was well wanted to see difference DP on car vs his JB+ stock-DP. Also, sprint booster is meant for older cars not ours that has extra power from factory and throwing boost in our cars (or tricking it) won't be wise if u want a healthy car.
