I am Freektuned for meth, but I also have a Stratified flash tune that I use from time to time for the crackles. At WOT, the Stratified tune jumps around 11.76 plus or minus ~.2. The Freektune hits 11.76 and stays put until red line. As for the temps, I cannot see what effect the WMI has because it's injected after the charge temp sensor, but I can tell you that after a hard drive, the intake manifold will be COLD. Also thought I'd mention that the meth tune pulls a lot harder into the higher RPM's. Definitely worth tuning for
