So im having a hard time finding a product i know MUST be out there.

Here is what im looking to do.
First off i want to put a computer in my car, got that all sorted out but i would like to be able to gather engine info (boost, egt, oil temp/pressure) which will take some gauges (was looking at defi to start) but i want to be able to write a computer interface to gather and display that data (Defi wont let you)

know of a gauge set that will allow this? something like the Defi Link system with a computer output?

Also i was interested in the Defi VSD. the VSD would be fine for just speed and RPM but if at all possible i would also like it to display Boost which it would then have to be part of the guage set (the VSD can hook in to the Link system to display some of that stuff)

Maybe im just dreaming but, i thought i would ask you guys.
