I’m aware and herd nothing but good things from the jb4 but after 2 engine failures from a buss and boost chip on a sonata it doesn’t give me the piece of mind I would like . When a proper ecu tune comes out I’ll probly get that but in the meantime I don’t mind the struggle if it means reliably =]
I’m aware I’m kind of new with all the car stuff just started going ham like 4-6 months ago haha and I herd something about the encryption on the ecu not cracked yet so I’m going to use the pro tuner until then but dare I say I drove around the block with it stock and I already want the pro tuner back in hahaThere are a couple of companies that offer ECU tunes. One is considerably cheaper than the Pro Tuner.
