Would the battery of the car was out for a long period of time, would the powerfc be reset?

How long would the battery have to be out in order for the pfc to reset?

Also, with the current mods I have on my car:

downpipe, highflow cat, catback, intake would i be save to run my car on a reset pfc?

would i be able to push my car as well and not worry about engine detonation.

 

mods are also on my sig.

 

i forgot it doesnt include your sig on the quick reply.

 

The PFC has an internal battery to retain the settings. It won't reset at all with no battery. The only way to reset it is under the Etc menu -- Initialize all data.

You should be safe at 10-12 psi with those mods. It is certainly better to get it tuned or to verify on a wideband though. If you are worried, you can raise the fuel 3% in the higher boost/rpm cells, but you should be ok.
