Just ordered my tune.

Can't wait wanna hear some good reviews, I did the 5.3 to 6.0 swap. I sent an email about wondering if it was ok if I ran my stock pm until the tune came?

It is possible, just don't beat on it.

 

[PunisherZ71]

Great thanks, how long do u think to get my tune?

 

[JennaBear]

Not sure what tune method you went with.

 

[PunisherZ71]

Traditional, with the core

Depending on when you ordered it, typically 2-3 days for shipping.

I sent my 5.3 Flex computer in to BB after installing a 6.0 **. I was down for exactly one week. The 6.0 ran ok with the 5.3 flex computer, but I didn't push it. You'll be happy. What parameters for transmission line pressure did you go with?
