408 up & running...vid/audio
Well it's up and running. So far so good. Feels stronger than the 6.0+100 shot. Still working on the tune. It's a bitch to stop it from surging in stop and go driving but it does ok otherwise. Here is a little vid of it idling with a few revs. 408rumble

Did you have to do any major wiring changes at all or was it pretty much the same. I am glad everything worked out for you, can u give me any heads up on anything I should watch out for during my transition, any info. would be highly appreciated.....
