How about this setup,
$479.99 Greddy Profec E-01 Electronic Boost Controller: I heard this controller hooks right up with the Greddy e-management system. No laptop required.
oh yeah, does anybody recommended possibly this: http://www.rageracing.net/Defi/Linkdisplay.htm

S7 5" TACH * 4-in-1
The Multi Tachometer utilizes all of the same design features as the standard S7 Tachometer as well as intergrates oil temperature, oil pressure, and water temperature measurements into the background of the gauge.
Built it Shift Light & External Shift Light
Then also run two extra gauges: for EGT and Boost.
Do you even need a boost gauge when you have such a sophisticated boost controller like the Greddy one noted above?
