Full tank is showing a 440 mile range now which I have never seen.
my 2007 gs450h has only shown 380 or 390 miles left on a full tank max. I average about 24.5 to 25 mpg and I drive slow

Doctorprius.com is in Virginia. There is another persn in Dallas TX if thats closer for you $550 for 3 month warranty up to $1600 for lifetime

Hi,

This is an old post, but incase you are still monitoring, can you specify what you mean by "the block assembly". Do you mean the entire controller box housing the DC/DC converter and hybrid ecu etc?

I have the same issues as you did before.

Thanks.
