What do I need to know about a reflash on a 6.0

[police251]

I am taking my 2005 6.0 PSD to ford on tuesday to have the computer reflashed.. The truck has never been to ford and has the factory program and I am sure that it is do for an update... I bought this truck about a year ago and have been doing all the maint myself.

Is there something I sould know before I take it and have this done. Has anyone else had this done and if you did is your truck running better. I am having a cold start issue and have checked everything ficm is good on power no problems at all. Injectors tested good the only thing I can think of is the program in the truck is out dated...

What do you think..........

New flash works well however fuel mileage will suffer. Power is down also.

Go for the sct if you don't already have it. What strategy do you have?

I believe the VXCF9H7 is the most recent. Depending on what strategy you currently have, you'll most likely suffer from loss of power and mpgs (some have reported losses up to 3mpg). If you have a tuner (such as the SCT) with custom tunes, you don't need to worry about the power loss. BTW, if you do have custom tunes, you'll need to get new ones if your strategy gets changed. The "positives" are that the new strategy will set a CEL if you have a temp delta of 15* or more between your oil temp and coolant temp. You should already have an aftermarket monitor for your temps, so this change is pointless, cuz you'll know long before the CEL comes on. The last major change is one that's actually beneficial. It cycles the VGT turbo at idle, so it "sweeps the vanes". This will help prevent certain parts of your turbo from seizing up during extended idling.

IMO, I wish my truck didn't have the VXCF9 strategy, but it was already updated when I bought my truck. The "best" strategy according to most, is the VXCF4.

Let me know what they charge you for a re-flash. I need to do mine to get rid of the bullydog footprint.

Usually it is about $100.

I have the new reflah it was done when truck went in for new ficm and yes fuel milege will suck big time and a very noticeble powerloss. It sucks

Why the major mpg difference... If this is the case then I will not get it done.. I still have the stock flash my truck has never been to ford in the last 3 years that I have had it. Is it really worth geting this done or should I just go with out it.. Can I tell them what one I want to get or is it just the new one and thats it...

If I can pick one what is the best flash to have... How can I tell what one I have is there a way to look.
