My '06 was, previously, an ok starter in subfreezing temps. When I last did the timing belt change, I also converted to the 5v glow plugs and a GDE eco-tune (incl the 5v glow plug program change). Since then, it's a VERY hard starter in subfreezing temps. I just completed a mod where I installed a heating element in the intake tube (you can do a search in this forum), and it did help a lot but not completely. We recently experienced rare, low single-digit temps here, and she wouldn't fire even with the intake heater on. I believe I hadn't put enough anti-gel in the fuel before the cold snap, so I'm sure that contributed to the problem. Also, I'm even more positive that not having an in-tank pump contributes hugely to the problem.
Before next winter, I'll complete the in-tank pump mod and I'll be able to get a better idea on my Libby's cold-starting capability. Hope this helps.

It is highly possible your current software may be your biggest contributor to your poor cold weather starting.
Just a suggestion, you may want to reflash back to your OEM software, then get one of Yeti's tunes that improves cold weather starting.
I think he extends the the duty cycle pulses of the GP's to improve cold start performance.
Some members on here have reported very good cold starting performance with his custom tunes with the modified glow plug programing.
Contact "Yeti" (Marco Giacomelli) on this forum using the PM or email buttons on the bottom of the post.
