I would give him a shot, I have a couple shops in the Houston area I've priced dyno times per hour and they were very reasonable. Reason for my response on $60 a pull is really high IMO. I know the last dyno day I was at it was 35$ a pull.
Do you have big stuff 3? If your talking about tuning the stock ECU it may be worth giving him a shot. The BS3 is not very difficult IMO.
I just learned of another shop in Sealy, TX this past weekend at the track. They have a awd dyno. DD Performance
Chassis dyno tuning is nice but not necessary unless your really trying to push the limits of the build/tune. You could set a goal on HP but it will all come down to the build/tune.
If you have BS3 you can email me a data log file and I can take a look for you.
