Hi all, I'm having a problem with my 90 GT and wondering if anyone has seen this. It has an Anderson PMS system, and an MSD 6BTM, and Vortech t-trim running about 15 psi. For many years this all worked great and was super reliable, but now it keeps burning up TFI modules. Other than the 6BTM the rest of the ignition is stock. One day the fuse to the 6BTM popped and the car stalled, so I plugged the coil back to the stock connector to get home, (engine is way down on power and breaks up bad around 4500 rpm without the MSD). Fixed the fuse, now it keeps eating tfi's! I tried a new stator, didn't help. Runs fine when it runs. My best guess is that the 6BTM is the problem, but at $400 for a new one I'd like to know for sure. Thanks in advance for any advice.
