It seems to be working good so far since.

I myself went with a remote tune through Frank Smith, and he's helped my car tremendously. We're still going through the final phases of datalogging and minute tweaking of the part-throttle driveability, but the car has come a long way thanks to Frank.
The original supercharger tune provided with VF Engineering's kits were atrocious 
My car ran like absolute crap. If I hadn't gotten the kit at a really good deal, I wouldn't have bothered putting up with their bullshit. Their customer service is horrid  |

As you know, I have the same issues (rich tune, stalling in cold weather). I have had the car stored, so I haven't tried to correct them. I was given the option to ship my ECU to them (I would pay, and take the risks associated with shipping the car's brain) or buy their cable for a few hundred dollars. I kinda feel like I'm paying twice and have had to deal with the issues in the meantime.
When I initially sent my ECU to them, the turnaround was acceptable. Responses from technical support have been mixed. I have had a few outstanding responses, and other times I've been ignored releatedly.
