I have Andy’s procharger set up with the guage pods ( all installed by Andy). always was about 59 to 60 mostly 59. Lately it has dropped to 52 at times hovering around 54. I have read in the past about "hot" gas or low fuel in the tank and that’s not it. Last time I noticed this, it was a full tank. I only use quality gas from Chevron or Union 76.

What should I look for? Should I be concerned?

Thanks

 

When was the last time you changed the fuel filter...................also I would recommend a Kennebell Boost a pump.....my car has 625 RWHP with A&A Set up (D1SC) and never drops below 57

 

Its not the fuel filter, and I do have a Boost-a-pump in there. I have STFA and I can't find the thread I remember that dealt with this problem. Any other ideas out there?
