we ran out of time because the shop closed at 6pm yet the car didn't get off the lift for the install until 7:15pm on the install day. Tech took a few too many smoke breaks during install so I had to pay the price (and sit there all day).

That makes it even more apples to oranges...
Also, that's a very veeeerrryy slow pull. I feel sorry for your engine. I dyno'ed mine on a Mustang setting the weight as 2,500 lbs and aero to 10hp and even then it seemed to take forever. Did they have it set up for curb weight or a timed pull? We always had to set the weight to 70-80% of the actual curb weight otherwise the pulls were too long and too taxing...
if all of that concerns you it shouldn't - you'd be seeing much more conservative gains in this case rather than some over stretched gains when they added the performance parts - not took them off. besides a tse-3 muffler and stock muffler aren't doing much performance wise anyway - the tse-3 was just welded behind the stock resonators. as for the adaptations - car wasn't driven at all as they bend one of my o2 sensors so I left it in the garage until I went back.
I don't work the dyno (either does Anthony). They do whatever they do because thats how they do it I suppose. They said they wanted a more accurate run in 4th gear so I let them do that instead of 3rd. I assume the weight has SOMETHING to do with the calculations of power and if it doesn't then whatever - it is a 60-120mph pull.
