Boost Gauge Install
 

Where is the best place to plumb in a boost line on my 85 300D?

thanks

Got my gauge installed and she is pushing 10psi. Shes nice and healthy! What other mods would you recommend for realibility and cheap performance?

Cheap gauges could be off that much, and a dial gauge is most accurate at 45-55%. so a 25# gauge would give you your best accuraccy for full boost

Ohh its not a cheap gauge. Its an autometer phantom series 2. How can I get my boost back up to 12psi?
