So.....

I bought an I3 8345 for my 07 Charger R/T as an upgrade from my Predator P2 7310.
The question I have is, (sorry if this is a dumb question)
After returning the car to stock is there anything else I need to do to sell the Predator P2?
I dont want to accidentally screw anyone over or ...

I know this is a very old post. but I just ls swapped a 5.3 into my 87 C20.
Who can I talk to about getting a tune for my stock swap?

I went thru the start up proceedure in the manual. tried to tune my 2007 Dodge Challenger R/T multiple times now. I keep getting the following message... "Calibration needs update please update tuner"
Tuner is showing its up to date via the Ignition program.
Predator P2 7310
What am I doing wrong?
