dropping fuel pressure on the rail I took my car this week to get tuned and was running into some fuel problems. The car made 423/405 on motor and 559/640 on 125 shot. When we sprayed the car the fuel pressure was dropping from 30 to 3lbs. that was with a guage on the rail. I still have the stock pump and 36lb injectors. What do you recommend I install for the pump. I want to keep in stock style in tank set-up. Any help would be thankful....

At 560rwhp, you are even at the limits of a single intank aftermarket setup.
You could try a Racetronix kit specifically for your car, which should support somewhere around 550rwhp. This may get you enough fuel, but there is no guarantee as you are right on the edge w/ your power level.
By adding a boost-a-pump to the above setup, you should be safe for another 50 or so HP.
The other option would be a twin intank setup that will support you well into the 1000+rwhp range. This is roughly the same price as a Racetroxin/BAP setup, but I cannot upgrade the kits above if you need more fuel later. If you are planning for more HP in the future, then one of the twin intank setup would be your best bet.
I stock the F-body pump kits if you are interested in either setup. Please give me a call if I can help you out.
