Does part throttle driving go to crap using this instead of an Emanage.?

 

It depends on the rate at which it is rising the fuel pressure, you don't want to feed to much fuel, it (r-rate) kind of has to be matched to the engine needs for it to work as good as some of the black boxes around.

 

What you want to do is pull the vacuum line off of it and set it at the factory static rate until you can get on a dyno or get a wideband, then you can run it with a turned down start pressure and have it rise 1:1 with boost.

Of coarse I assume you know that you will have to convert to a return stile fuel system right?

Ultimately what you want is a return line with a 1:1 FPR and a emanage/power paq/fuel computer of some sort to lean it. You could also could just go with a Map clamp to lean it out then you would also get better timing, but this method allows for less control.
