the jb4 hardly just "throws a few signal modifiers" onto the signals. burger and Vishnu were the first to crack the dme and though I'm not saying Cobb didn't do a great job or anything, the two big piggyback tuners coming out with tunes and working so fast to crack the ecu shows dedication. Cobb is great but at this point jb4 simply makes more power and while its harder to install at this point I can install it in the 20 minutes I'd be sitting there waiting for the software to upload anyway
