i have a racetronix and right now i'm not very happy with it, cause when I whack the throttle it drops to 53 psi. When I had external T trex pump with my stock pump I ran rock steady 60 all the time.
I'm thinking the shop that put it in for me, installed something wrong.. I've been told its the stock regulator but I'm not so sure.

When I had my Racetronix’s it did the same thing……
The reason for the FP Reg being at fault is its in the wrong spot on the car…. Its at the tank and it should be at the rails where FP should be read….. so after fuel leaves the Tank and FP Reg it has no idea what FP is ta the rail.. ie what the car is demanding at the motor….

The reason for dual –8an lines in the sump kits most sell are both dual outputs of 3/8 npt fittings…… there for you use a 3/8 npt fitting with a male –8an fitting and then run both of them into a Y-Block to feed the –10an line.
Then the Y-Block up front to feed each Fuel rail… here again the rail is 3/8 npt….
So the same fitting is used and again.
Hope that clarified it for you.

But 200 seems like a deal for all of the work... I'm gonna PM you this evening.
Anyone running a sumped 98 tank w/catback? Even with the sump cut down, it still looks like a difficult fit.

Im sumping my stock '96 tank with a Competition Engineering sump... I basically notched it to fit the contour of the tank and clear my muffler. No big deal, just some patient work scribing and grinding. CE's instructions recommend a tank sealer from the Eastwood Co. which I'll be using on my tank after the welding is done.
You really should base your fuel pump decisions on the amount of flow needed and at what psi you need that flow. For my setup, I needed 600lb-hr of flow at 60psi (Fuel pressure + boost pressure w/ 1:1 reg)
An A-1000 would have been too small and an Eliminator would have been overkill and either would have required a pump controller to help keep the fuel cool.
My setup will consist of a single 10an line from the sump to filter to y-block, then to parallel plumbed Walbro 255's. After that, another Y-block to a single 8an line to feed the rails. At the rails, Im using a tee but a y-block would be more efficient if you have the room. From each rail, Im running a 6an to an aeromotive reg.

If you want to better control of your fuel pressure and don't mind spending some money on your fuel system you could try a set up like mine.
I have dual Walboro 255's intank and run a modified Z06 intake and fuel rail system with an adjustable fuel pressure regulator (mounted on the rail). My system uses a 6an line from the fuel rail back into the tank. I have Mototron 65 lb/hr injectors and pod mounted autometer pressure guage referenced at the fuel rail.
The way my system is set up means I can control fuel and maintain a constant pressure throughout the entire fuel system.
