Cold Start Issues, IDP tunes, VXCF9

I'm having some really bad cold weather starts here in Wyoming, and believe me, it isn't even cold yet by our standards. If I don't plug her in, the starts are awful and it just plain doesn't want to drive until warmed up to over 100 degrees for EOT/ECT.

Here's my dilemma:

2007 F350 6.0, 44K miles, IDP tunes, turbo-back exhaust, no cat, 4" lift, coolant filter, Edge Insight CTS, VXCF4 strategy

I'm at 4500 miles on the current oil change and I'm taking the old girl in on Monday to get the bed plate leak fixed and get the sticking speedometer replaced. Bed plate is under warranty, speedo is not . Obviously they will change out the oil, I'm running 5w-40 T6 synthetic and for this go round I have picked up a couple of bottles of Rev-X in the hopes that my cold starts are stiction only and will be fixed by the Rev-X. I'm also contemplating getting the stock flash update to strategy VXCF9. My problem is I have IDP tunes that are written for my current stock VXCF4 strategy. I have combed the forums up and down and still can't get a straight yes or no answer on the VXCF9 strategy.

Question #1:
Does IDP write tunes with VXCF9 yet?

Questions #2:
I'm in definite need of cold start help and VXCF9 is supposed to help with inductive heating, is it wise to update to VXCF9 or should I pin my hopes on the Rev-X?

I ask because I won't be charged for the flash update from Ford as long as the truck is in for other repairs. I also don't want to do myself a disservice with the update from all the negative reaction to any stock flash above the VXCF4 strategy.

Thanks all in advance for any insights and happy Thanksgiving!

Just curious as to how much Ford charges to flash update your truck?

If it were me, I would get the flash if it fixes the problem and not worry about the tunes.

Here's my advice to you:

I amy be wrong, but when the y fix the bedplate seal, don't they remove the cab or engine? If it's what I'm thinking of, I'd find a dealer that'd install ARP's and an EGR delete. I could be thinking of the wrong thing though.

Second, be sure to provide them with your choice of oil when they fix it, otherwise they will just put Motorcraft 15W-40 in it, and make your cold starts even worse.

Thirdly, I would not get reflashed. Use the Rev-X and you should be good to go. Along with improved cold starts on the new flash, comes terrible fuel mileage. I would know.
