I'm Awesome
I'm not interested in a tune I find on a gas truck there a waste of money I've had gas trucks dyno tuned with exhaust and intake mods to just have $700 less in my wallet. I think my next thing will be mpfi upgrade and new fuel regulator looks like a pain in the A$$ of a job. However I do find unless my truck is plugged in when it's cold outside and it's its sits overnight it won't start it just cranks over but if it's plugged in it fires up the second you touch the key. I was told it could be the temp sensor by the thermostat so put new one in no difference also had a shop do a fuel pressure test and said it was very good well within spec for the 5.7 vortec. So only thing I'm thinking is the fuel injectors and regulator. Why like to get to the bottom of this as I'm confident this truck should be getting better mpg and have more power then it does. And when I did the plugs they were bad it ran lot better after tune up just didn't change mpg at all it did look like I had a couple cyclinders running a bit lean there was touch of white on three plugs. And the truck also has all new 02 sensors.
The problem with this statement is assuming all tuners are the same. There are countless stories of people taking their vehicle to get a dyno tune and then comparing the changes from their stock tune and seeing very little improved, or in some cases made worse. It is like every profession, there are good and bad tuners as well. I do my own tuning and while I have made improvements I would not call myself a tuner. Your best bet is to find someone that has a good reputation, I have yet to hear a negative experience about Black Bear, but I have never used them myself.
My only point is that you may be doing a disservice to yourself to write off tuning because of 1 incompetent tuner in a industry filled with them.
