Veeeight/ Jasso86 - thanks for this, I now see the balance. I guess as many have alluded to - its what youre comfortable with I suppose.
TBH, I spend my dollar with MTM as I trust them and know they have huge backing and a lot of goodwill to protect. I know they were the factory rally team/ audi partner of choice back in the day of Group B when they done all the mapping and fuelling of the mighty S1's!
The MTM-Cantronic appears and is reputedlty very sophisticated with respect to others; Its not just overboosting. It has a cold oil temp soft limiter, removes the 155mph limiter and, well....comes with a MTM pen and badge and inner ful cap sticker
I am using the MTM in the S3 for the last 7 months and did 25000km with it.
It works ok and now is the best way to have fun with the CXJC.
I took the MTM because I had 2 cars with their boxes and had no problems.
The main purpose of installing it , is something called warranty.
For sure the best way is a remap.
I am considering when good software appears for our ECU's to sell the MTM and buy another ECU and play with it.
PS: MTM box does not remove the limiter.
