There are already a couple hundred Rev2.5s on the road. Just make sure you are running the dedicated Rev2.5/Rev3 maps. If you run the old Rev2 maps, you will have all sorts of misfire related issues due to changes in the ignition control setup (voltage thresholds are now higher). You'll notice that there are two subfolders in the download folder, one for Rev2 and one for Rev2.5/3. If you continue to have a problem or need help, give us a call tomorrow and we can help you.
Cheers,

Shiv,
Thanks for the reply. I'm running the maps that were loaded at Vishnu when my unit was sent back for the upgrade end of last week. That's why I asked this question. Either I've got something marginal going on with my HW (Plugs, injectors, something) or there is some other issue with what was loaded... I can try reloading the 7-29 Rev 2.5 maps, but am not sure what else to try after that.

Whats the story with these upgrades? Has anyone upgraded their Rev 2 to 2.5 and still using the PPS meth kit? If so how is the car running? Is there a noticeable difference?
