yea the first firmware v6 170 was total trash. rattled a fee piston oilers out but that was it. besides time and money. cost me a few grand worth of wiring harnesses, plugs, coils, head gaskets. 220 build firmware came out and my car ran like a monster...till i opened a datalog after a perfect street hit. never ran right again until now. i uploaded a fresh tune and ive had zero sync errors in about 10 minutes of logging everything. cant be happier but gotta move my coils back and see if it returns
