People with Fuel Pressure gauges can you tell me the stock PSI and anyone thats running a 2nd piggyback pump what your PSI is? Thanks

 

Around 28psi at idle.

 

From service manual - 27-37 PSI at idle

 

28-30 pretty much constantly. It bumps up to around 40 when the KB boost-a-pump kicks in.

 

Thanks guys. I just installed a Vortech HO kit over the weekend. Im gonna get a Boost, air/fuel and fuel pressure gauges to make sure everything is good. Dyno is next hopefully I will be over the 400RWHP marker!!! Runs like a bat out of hell!!!
