This run was increasing RAM boost target to hit a solid 29 - 31 PSI of boost up top, which is absolutely where boost should be given my setup.... shouldn't be an issue at all to run this boost with full E85 and the BMW WMI running strong as an added safety net ...... or so I thought; Sigh .... please see above log ..... Still can't hold boost above 5K rpms after Cary said "ah hah I found out why boost was dropping we are good to go" .... Moreover, I'm noticing a very disturbing trend after my wife and I researched this exact same problem for about 6 hours last night .... This notion of mysteriously not being able to hit boost up top, which in the vast majority of cases a resulted in random and undiagnosed misfiresis a very prevalent theme with Cary .... I was on the M3/M4 forums literally all night last night reading time and time again about customers having the exact same problem up top, whereby the car either completely misfires and you cant push above 5K, or it do,es allow you to rev further, but both power and torque literally go to shit (recall my last dyno). My wife and I have compiled 8-10 different instances with Cary where this has happened to clients and they are left high and dry with no solution ..... Im not saying its 100% his fault ... maybe its the VTTGC turbo???? But it seems fishy ....
