I've had my car tuned with LS1 Edit awhile back. I'm getting my Fuddle 3600 2.2 str stall installed next Friday. Although i'm planning to get it retuned again since it will be free, how much difference is a tune really gonna make? Is it likely to run like crap, have SES light, bang the rev limiter and shift poorly? FYI, when my car was previously tuned the torque mgmt was zeroed out, shifts firmed up and shiftpoints raised slightly.
