I've got a FLT lvl 5 60E and I think I'm about at the limit with it. A couple of months ago Allen and I were trying to dial in a boost controller and saw 14 psi a few times before the trans started complaining. After the 6.0L swap, I'm nervous to put the 75 shot on it. Every once in a while it will complain (slipping on hard launches) but it's held so far. I haven't been to the track since the engine swap...I'm putting in an 80e as soon as I can afford it.
