Seriously.
Aren't most of the people complaining about the speed of their work, for stuff done in their shop? I bought something small from them once, and I got it pretty fast.
Seriously.
Speed: It is slow, but so was the worn V8/auto that was in there before. The V8 cruised better at high speeds - it was quieter and more relaxing. Acceleration is somewhat similar after tweaking the injection pump (but I'm comparing auto vs manual and worn vs fresh engines). I've hit 80 with the Tdi but only just to say I did it. 65 is a nice cruising speed and EGT's are around 750. Trying to climb mountains in NY/VT/NH will send the EGT's over 1000 pretty quick and maintaining the speed limit can be a challenge, especially if you're loaded with people and gear.
