Anyone have a bad racetronix pump {new} well my saga continues 
My car is having fuel pressure problems at TTP. Matt say's it will have pressure at idle then when you hit the throttle it drop's pressure sometimes 5-10 lbs or sometimes it almost loses all pressure then sometimes it ok till around 3500rpm then it will drop. They said all grounds are good and voltage is good as well. This set up has less than 1 hr on it. Has anyone had a problem like this or any idea's??

I've got one on the bench ready to go in tomorrow... I sure hope this isn't a common occurence. That'd make me sick. Especially after all the time spent swapping motors. My fingers are crossed....

Yeah like Bob said. I'd check or have your shop check the lines in the tank. I was told if it wasn't done right my pressure would be off, by Thunder Racing. Basically there's a very small line that attaches to the actual stock pump that has to be cut and put onto the new pump. Second, there's the white bendy-straw looking hose that needs to be clamped down with a worm clamp in the assembly. If they're not sealed well they'll just spew the fuel back in the tank.

Not sure if this is related but I have a Racetronix P&P with a MSD BAP. After a great initial tune and 3500 flawless miles, it now is fluctuating 5-15psi very rapidly from when it builds 8-10psi of boost. I have not had time to log any data but I'm sure it's in either the BAP or the pump.

BTW E-mail for customer support SUCKS!!!!! I wish i knew this before i bought cause i asked Racetronix to call me several times so i can get there opinion but i NEVER got a call back. Just some emails. My new motto is if they can't talk to you don't buy from there
