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.

2000 Mustang GT Steeda build #48. Bolt ons, suspension, Novi 2000.
Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
