The FIM chip is about the best chip out there to put in your ST , from what I have heard. I have no experience with other chips. You can have the stock chip flashed at a dealer to try to correct your problem. I purchased the 161 for my 98 ST and like the performance.There is a sensor that feeds air temp and barometric pressure to the ecu, I wonder if changing that would help?
