Ok so I installed my Jb4 anti-lag feature on my 2008 335xi AT N54. I am FBO+E85 (E60 gas)+ inlets on stock turbos.... I tried this out and it works but it tends to spike my avg_ign when I let off the volume down button and go. I run a custom map 22 psi midrange and 18 at redline (pretty much maxed out). Is this 35 dollar kit NOT really meant for stockers as there is not much lag as it is? Also if I try to use it on launch hold the button down in 1st and let off is that a spell for disaster? I am AWD and I launch in 1st full 22 psi but before this if I put to much stress on the launch (anything spooled up above 5 psi) the transmission would go into 2nd when brake boosting no matter what. I am xhp stage 3 flashed but wonder about my transmission sometimes. I just don't want to launch off the line with 22-24 psi spooled up and shatter my driveline components as it will grip like all hell with the tires I run plus the awd....
