When to switch to a aftermarket ECU?
427 Dart lsnext
GT55 turbo
E85

ams500 boost controller
Presently running mid 9's on low boost, the plan is to be running mid 8's next year. Presently on the stock pcm. How do you decide the time is right to make the switch to a aftermarket ECU? Interested in the Holley set up.
I don't see many limitations with the stock PCM in a 99+ car, and in a 98 it's a pin swap to go to a 99+ computer.
