anybody have any issues after the svt focus pump install. I put on in my 4.6 2v.. i feel power loss between 3000 and 4500 rpm. i dunno if it is getting to much fuel or what. anybody have any issues?
Do you have datalogging available via the Diablo handheld (Predator?)? If so, log RPM, load, vehicle speed, MAF, STFT1, STFT2, fuel pressure, and fuel pump duty cycle. Add more parameters, if necessary. Data will be very helpful in seeing what is going on with the fuel system.
One thing I have always heard....if you put the Green Top SVT Pump in, you have to retune the computer. This pump provides different flow rates at different pressure vs the stock pump.
