Well after a couple minor setbacks I finally got to pick my truck up on Tuesday to start breaking these things in and all I can say is "WOW" :--) These things rocket from about 5lbs of boost all the way to 60lbs in a split second, you definately need to learn how to re-drive your truck. Egt's on level 5x5 EZ on 2 spike at about 1350 and then start to drop; accelleration is amazing and spoolup is very good I cannot wait to put this thing back on the dyno and see how much more I have gained but it really feels like allot. Installation was very thourough and professional and these things look just as good as they perform. Thanks laserbob and Nathen for putting in all those the extra hours getting this things done, I owe you one. Mike
