I'm not convinced there would be much benefit to anything other than swapping the accordion pipes out of the intake tract and switching to a GTX series turbo. And unless someone really wanted my turbos bad enough to pull them off and install GTX turbos in their place (seanK???), I am completely content with everything as it sits. I do plan to replace my removed carPC with a Windows8 intel based tablet PC connected to a USB hub to do all the Nistune datalogging and finally do something with all these 0-5v outputs that are going to nowhere now (dual WBO2/EGTs). I'm trying to wait for the new Intel Haswell based tablet PCs to be released after June though....
