Quick OS question

I just recieved my Flashscan personal. From everything I have read so fr on these boards it seems that it is better to upgrade to a custom OS over the stock OS on a 1999 Trans Am.

My question is. Will I need to aquire another PCM from a newer T/A such as a 2001 or can I upgrade my current 99 PCM?

Thanks in advance
Shawn


Back to reading. 50 pages in general chat takes awhile..lol

Welcome! If you have personal you will need to upgrade it to commerical to be able to flash in a different or custom os. You don't need to aquire another PCM as that would be more expensive then just upgrading to the commerical version.
