Recently had my Forge DV switched over to a Revision G at the request of the highly knowledgeable R-Tech.
The first thing I noticed is how the Revision G seemed to improve mid range boost, but over the whole power band, wasn't nearly as impressive as the Forge.
My car had been under vacuum for 70,000 miles so it probably took a little time to readjust to going back to electric controlled, but it's still not as good.
The second thing I noticed was the bizarre noise the car now makes on initial boost, almost a squeaky whistle, that flutters. If I accelerate and then come off straight away it's very noticeable for that short period of acceleration. Any ideas on what that maybe? Is that just the sound of the Revision G?
