The PO of my E99 F350 PSD said he had a Superchip installed (along with bigger exhaust etc, beefed up traans,but no gauges) but doesn't remember much about it because it was something his mechanic did.

He doesn't have the turner or the box it came in or anything. No idea what model it was.

I want to use a turner that gives me choices. Lets me select the state of tune I want.

How can I tell what has been done to my PCM and how can I delete it. Will one of the new turners over ride the old flash on the PCM (I think it is a flash, I havn't removed the PCM to inspect it and see if there is anything installed on it).

I was told that my first move would have to be to take the truck to a dealer and have him reflash it back to stock. Is this true?

Thanks for all the help.

 

call a dealer near you to see what the latest flash would cost.

 

Thanks for the tip

 

I sent it to Riffraf and had it reflashed. Took me ong enough to get around to it.
