Great review benzy. I am currently working with PTF on an E40 map as well. I am still on the first map and I am patiently waiting on the second map to come over so we can move forward. Luckily, Jake will be down here in December so I hope to be able to meet up with him to fine tweak the E40 map and possibly do a 93 pump map as well.
I really wish I had found these guys a couple of months sooner since I paid $475 to get in on a Pro Tune group buy only to be sent home after driving an hour and a half because they were unable to tune my car suspecting a turbo issue. They gave me a $300 refund which wasn't enough since it was clearly tuner error. That same car with the same turbos was trapping 115 mph my first time at the track a few weeks ago. I won't put them on blast though since I like one of the guys that works there.
