Re: Powertrain Control Module Flash TSB #18-030-04
My Crossfire is build 4500 something. I also didn't get any engine light, but felt it was very sluggish, bogging down during acceleration. They checked and said it did require an update! Re-flashed and I can tell you it made a big difference! Much better throttle response, low and high RPM's. It seems to breathe better.\
I also installed the K&N filters after this. I believe this also improved air flow, it even sounds different! Off the subject but I install the Mopar/Borla Catback system Friday, can't wait to check it out! Good Luck!
