Fuel pressure is a must if you are going boosted. Also oil pressure and water temp are pretty much mandatory for any setup. Mechanical if you can for the oil and water.
You should be running at least 5 gauges for a boosted app:
2000 Mustang GT Steeda #0048 34k miles. 99 Cobra 4V swapped, FTBR IRS swapped, exhaust, tuned by James Gordon.
Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
