Sounds like you where running out of pressure honestly.

I went to the track last night and watched the fuel pressure and at around 5000 rpm my fuel pressure was @ 20 psi
. What do you guys think....run another intank pump on a switch or should I hook up that booster pump that comes with the procharger?

Re: New dyno numbers
I was thinking about buying the racetronix plug and play kit for a blown 383 set up also...... however if you don't have enough pressure I just may have to buy the dual intake pump.

Re: New dyno numbers
System should be good for apx. 550RWHP FI at 43.5PSI base.
Running the FP too high will greatly impact the fuel volume.
If you need higher pressure due to undersized injectors you may add an in-line pump to maintain volume at higher pressures.

Re: New dyno numbers
I thought that I had read that an in-line pump on a racetronix kit or any other 255 pump would be like putting a firehose through a straw. I have emailed you about the dual pump setup BTW

We are not making DP's at this time. We are setting up some dealers to make them in-house with our harnesses, pumps, plumbing etc.

Re: New dyno numbers
Did you run any DataMaster logs on your passes? I fought fuel pressure problems for a long time and finally figured out my alternator was crappy out at high rpm. Check the Voltage on your logs this may be your issue to.
