a doubt. to tune the ECU. What is the best option for this model?
Read the ECU and send the original file to a specialist of this electronics to make the modifications?
Or buy some GAN-type interface, (these already have a modified SW loaded)
I also see 2 versions 450 and 466cv, how are they different?

I am a programmer, and I have all the machines for this job, but in this case I don't know what would be better, read the ECU and send the file to my collaborators so they can modify it. or directly buy one of these devices that already has the modification inside.

I'm sure that the best thing to do is to do the tuning on a power bank adjusting it to my car, but I don't think it's necessary since it doesn't have any modifications.

Having an experienced tuner is always the best option. Read the ecu, send it to the tuner, and they'll send you a file back to upload.

Those handheld tuners are okay.

Who is one of the best tuners for this model?

9sec

are you us based? the type is strange way to ask . if your us based hp tuners is the go software to tune and store datalog on this platform. canned tunes wont help have a proper shop tune the car since its not just power based the trans gets a tune as well

The dirty little secret is that HP Tuners is for serious hobbyist and shops. There is a LOT of knowledge necessary to properly dune with that program, and if you've ever perused a tuners forum, even the experienced people have widely divergent and extremely heated disagreements on tuning protocols. It is ill advised to buy the program and jump in and try to start tuning the 1 car you will ever work on.

Canned tunes can help to a certain extent if you have a very short list of very common mods, and you are not going to push the envelope in any way. Trying to get max number with a canned tun is an exercise in frustration. The very best tunes come with the shops that do a dyno tune with a wideband O2 sensor AND (important!) also include some street driving for that real-world effect on numbers. Dyno tuning is great for those top power numbers, but street tuning is the most environmentally accurate way to tune. Dynos can’t replicate all the environments you’ll find on the street.

But with a HPtuner and AFR sensor, you can have it tuned remotely. You just have to rent out a dyno. I think the first step would be figuring out your mods and that would dictate what your tuning needs are.
