I know it's Nelson country, and he has a great rep no doubt. However, Texas is quite a drive for us Ohio guys. Plus a mail order tune vs a dyno tune = No brainer for me. If you go to SilveradoSS.com that's PCM4less territory. These guys all seem to have a pretty good grip on what's up. To each his own, but I have to thank Nelson for being a site sponser and helping to give me this forum. Thanks!!
