Jetta VII
I have a mk7 jetta 1.4t. I'm trying to decide the best tuner to go with as far as hp/tq. I've been doing research into APR,COBB,UNITRONIC,JB4,RACINGLINE, and RaceChip. I'm looking for best bang for your buck. Something with lots of features and comes with set/custom maps. 1 price for many tunes...
