SVT with boost no longer needs B-A-P

I have found a way with the tuning software to make fuel psi go up with boost and go to 60psi and was still going up with the stock SVT pump and NO B-A-P added

It also proves to me again thet the fuel pump dutycycle shown in the PID isnt correct because I hit 100% fuel pump dutycycle at about 4500 yet the fuel pump kept going up on fuel psi

I am going to play with these changes with a ZX3 now and see if they will work there also

Tom

Tom call me... I also found something VERY interesting with the fuel pressure.... I HELD a constant 80psi earlier today.... it was an accident but I do know how I did it.... and I also had the BAP turned off.

Now hurry up go find a way to do it with the Zetec So does that mean that there is no need for a return style fuel system?

I'm kinda wondering if it's the same adjustments that i made to my tune to hold the appropriate fuel pressure. Be kind of interesting to see what adjustments these are

Does this mean, a return fuel system may not be needed for more than 350hp per say?
