Vacuum/Boost gauge with Edelbrock E-force?
I was curious if it is possible to install a vacuum/boost gauge for an Edelbrock E-force supercharger. According to their tech, there are two points where boost can be measured but no mention of vacuum pressure. They also advise against tapping into the vacuum lines on the driver's side or meesa bombad Jar-Jar things gonna happening!
Any thoughts on this? This sounds like boost gauge only. Oh, and I'm a noob so feel free to explain away.
For reference, my car is a 2010 Mustang GT with the 1582 Street Legal E-force unit, cat-back Magnaflow Magnapacks, Hotchkis sway-bars/adjustable panhard bar, and Eibach Pro Street S adjustable coilovers.
Thanks.

According to Edelbrock:
E-Force Boost Measurement (Installing A Boost Gauge Or Pressure Tranducer)
1. The TMAP sensor mounted on top of the manifold at the rear of the driver's side, outputs a 0-5 volt signal through pins 1 & 2 (pin 1 is signal & pin 2 is signal return,) that can be converted to an absolute pressure reading using the below calibration curve. Use of this signal requires an ambient pressure correction for calculating boost pressure.
2. The second option is to utilize the pressure port at the rear of the passenger side intake runner flange. Your supercharger has been pre-drilled and tapped for a 1/8" NPT fitting. There is currently a plug sealing the hole, which can be removed, and replaced with a fitting to adapt to your sensor.
CAUTION: Never cut into the vacuum lines leading to the fuel rail pressure sensor and bypass actuator, on the driver's side of the manifold, for the purpose of tapping in a boost gauge. Interruption of the vacuum signal to the fuel rail pressure sensor can affect the fuel pressure reading to the PCM, which can result in engine failure! Furthermore, this port reads pressure before the intercooler, and therefore is before the inherent intercooler pressure drop. Readings from this port will always be approx. 20% higher then what the engine actually sees.
If measured properly on an otherwise stock 4.6L Mustang GT, your boost readings, utilizing an electronic transducer or MAP sensor, on a dyno, should be comparable to this boost curve, http://www.edelbrock.com/automotive_...ce_boost.shtml, collected from a recent dyno test here at Edelbrock. If you install a mechanical boost gauge in your vehicle, you will see a steady 5 PSI on the gauge during full throttle acceleration on the street.
