since we're talking about pumps I got the WALBRO 255 GSS342 pump and i was just wondering if i need to make any adjustments to the fuel pressure or is it ok to run the stock stuff with the 450cc and the hack?

Re:255lph or 190lph, HELP!
 

I say keep the stock pressure and if it isn't enough, then up the pressure; but you should be fine with stock pressure and AFC hack.

Everyone has had sucess except for me with the AFC settings on the forum. Every car is different but I am sure you'll be fine with stock fuel pressure.

As for fuel pumps, get the 255lph. Your car will only use the amount of gas it needs and return the rest of it back to the tank. You could have a 1000 lph fuel pump and your car would run the same because the bigger fuel pump only means that you will never have fuel starvation.

Do it right the first time and you'll never have to worry about it again. ;)
