So I finally switched from Bama to Brooksspeed. I loaded the tune and did a datalog. Now I have a P0605 check engine light. Says something about the PCM. Is this a big deal? I searched on here a ltitle bit and most people said its not a big deal comes up when u flash a car unless u turn it off.

Dont you mean " brenspeed"? Did you call them. When you loaded the new tune did you return to stock 1st?

The same happened to me after a reflash.
Contacted lund and had an updated tune 5 min later.
According to Jon its no biggie.
