Default Post Racetronix Install Question????

SO - My stock fuel pump was holding at 56-58psi until about 5400 RPM and dropping down to about 48psi...

I purchased the Racetronix kit and installed it yesturday, Now the car holds 62psi just driving around....but when i get on it it drops down to about 52psi regardless of RPM...

Does the car need a re-tune after the racetronix's install to maintain pressure????

That pressure does sound low but I don't see how the PCM could control the fuel pressure, have you talked to who ever you bought the pump from?

My racetronics acts the same way, I thought it might be due to the larger injectors with the S/C. It seems like NA cars W/racetronics don't drop like that but mine does.
