Generally speaking - a simple "mail/send in" tune is not the way to go for cars this age.
We must accept the fact that we are not dealing with new vehicles anymore. Hoses become brittle, parts are worn out and overall time took its toll.
With the P-Bus in place you can independently verify the integrity of the setup, since it provides logging abilities and also shows you the so called knock and misfire counters.
When going with a handheld like the MaptunerX you are definitely getting a superb tune, but in case of an issue you have to rely on a Tech2 or actual experience to determine what is wrong, while a log file can be simply shared.
As said - absolutely no hate on Maptun here - their software is one of the safest out there. But for me personally the ability to verify what is going on is important.
Regarding the question - why one should buy from our competition:
I think every company has their own benefit and also approach to things in general.
Noobtune as an example offers very inexpensive files, which is exactly what you want for a low budget tune. But don't think that low budget means that it must be poor quality - I would actually say that price/performance wise Karl (thats the name of the guy behind Noobtune) probably beats us all.
Maptun on the other hand is expensive.
For that you can rely on tunes, which were created on the dyno and approved under various load conditions in hundreds if not even thousands of cars. It is simply a quality product, where you know 100% what you are getting.
Mackanized (mackanized.eu; you can also check his Facebook page:
Mackanized & Co) is something in between the two. Markus (mackan) is a man of precision and has exclusive knowledge about how the Trionic works (especially software wise).
We as a retailer of his work (thats what I meant with "us") provide extensive support and verify every car tuned by the log work mentioned above.
By the end of the day it is up to you to decide where you feel the most comfortable and what exactly you are looking for. Of course the files will be different, but they will still perform.
Personally I think you can get an at least equally good product from our competitors. So in all honesty - go for whichever you want.
The only thing I try to prevent from happening are people who get scammed by some Facebook tuners, who sell stolen Tuning Packs from trionictuning.com or copy-pasta of actual professional tunes.
Which is why I rather give a customer away to the actually good and fair competition by being honest about it.
