Don't shoot me down! But I'm gonna say it!
As long as you go to a reputable company not some back street cowboy, isn't a remap just a remap, there's only so many parameters that can be changed and tweaked,
Friendly discussion remember ,Iv not coming me on here to step on anyone's toes. But is there any hard evidence that the R-tech maps are superior and worth travelling the length of the country to obtain.
Hard evidence is a tricky thing to claim as a lot of this is subjective - people hold R-Tech in high regard because they're very happy with how the map feels.
I agree, you're getting into murky waters if you say "R-Tech's maps are better" than another tuners.
However, when there are so many positive reviews going back a long long way, their maps are proven to be safe and strong, and there are thousands of happy customers, including those who have switched to R-Tech from another tuner's map, it's hard not to see them as one of the best if not the best option.
There are lots of good mappers out there, but they may be less of a known quantity than a mapper that has built their rep on the back of a proven product over the years.
I know Shark do good maps for TFSIs. Along with Unicorn, and Vince at Stealth.
I'm on an R-Tech map, after doing loads of research and asking loads of questions, and it's brilliant - I know I made the right choice. I'd always recommend them.
