- dynos are totally unnecessary if you are a good tuner and it's not a race car upper limit type tune.......but oh boy do they cut the time spent in half. three or four pulls can replace hours of road tuning. (unfortunately for me, the closest dyno is hours away)

- there is no such thing as a simple tune. 'i just need you to fix some codes' can end up being a massive job. so never quote before you have all the facts

- many people asking for tuning are just a charity case at the total mercy of some hotrod mechanic that went ahead and installed a bunch of crazy modifications, then went 'uhhh... oh... you need to have that tuned too, but we don't do that'

- even after pouring blood sweat and tears into their car, many builders want to separate themselves from the tuning process, and simply don't care about what you're doing as long as it runs well and makes power. if you try to explain even basic ignition timing to someone like that, they glare at you like you are a nerd

- tuning totally unfamiliar engine platforms is almost always done at a loss, even if on first glance it looks like other things you've tuned, and you need to think of it as paying for your education

- people get really upset when you tell them their car is way too broken to work with, or that you simply don't want to get involved because of all the cheap crap they've bolted to it

- the worst vehicles in the universe to tune: anything made by or related in any way to the Chrysler corporation. no joke. next time someone says hemi im hanging the phone up.
Lol, I have tuned 4.7L and 5.7L Mopars with NGC4s as well as the older JTecs on the 318, 360 and 488 and older 4.7L. Worst vehicle to me to tune is anything GM since they went to torque demand.
