1. Why do you say that? It should take no more than 30 min to create a good tune. Considering you have value files with your typically changes for a Engine family.

2. Dont forget 25% to the DBW Table I couldn't agree more, it just a way of marketing tunes. Economy tunes are Myths...

3. No doubt! There are some great books out there for EFI tuning.

To hopefully answer your question in bullet one, cars constantly change and no one car is the same. Using old files like some companies I know of will not get you the desired results. Theres a reason why Vortech is asking for 10 2014's instead of 2013's, templates and parameters were tweaked, although slightly, it still manipulated driving characteristics and altered tuning strategies.

 

I agree that no two cars are the same. But when it comes down to email tune differences that can be debated. You typically don't change any perf tables between two calibrations of the same engine family. (By engine family, I'm referring to engineering p#)

For example, in a typical tune, what would you do differently between two 2012 Mustangs with exact same trim, just different Catch code?

Now, there is some truth behind the differences in calibrations. For Example, ZFK0 -> ZFK1 may require changes to the engine itself, such as EVAP. That would be the reason Vortech wants 10 cars, so they have all their bases covered.

However, in all the debate, there is no tune better than a Dyno tune.

I disagree for the 2011+ cars. With widebands from the factory data logging a tune on the street is the way to go now.

 

Yea and No, I dont want to say that because trying to do a 3rd or 4th gear pull to redline and get enough for datalogging on the street is not so safe (pay attention to traffic) and can skew results/data.

For cars with bolt on mods, email tunes are definitely the way too go. A dyno tune may be a better option if someone is running a super, turbo charger or nitrous. Although , I have been recently educated on that and with some data logging with having a super, turbo charger or nitrous email tunes from Lund, AED may be just as good as a dyno tune.

 

For those who are not trying to squeeze every last ounce of power out you are correct. Email tune are supposed to be the safest. (I say supposed because some dealers are idiots)

Same goes for a boosted car, you can get away with email tune. But you're not going to squeeze every bit of power you car has with one.

Well, you may be right about squeezing every ounce of power out. For those who don't track race for competition, then getting that extra 200th of a tenth really doesn't matter. Majority just drive to and from work. Then off too Wally World too pick up toilet paper, milk and bread.

Unless I can see huge acceleration gains in my stang from a custom dyno tune over my email tune , no way I'm paying around 400 dollars for a dyno tune and that's with me already having the Sct tuner device. I personally am plenty happy with my MPT email tune for my basic bolt on mods and my driving habits.
