hello im teddy from elkhart indiana i recently finished my t3/t4 turbo ls build and am running a chipped p28 with a turbo base map.I am having trouble finding anyone in my area to help me get this beast dialed in.I have a plx300 wideband already installed.The car runs strong to about 5lbs than heads toward mid 14s on afr…not good !!Im not sure if its the tune because till it gets to 5 it runs 12s on afr ,or if the pressure regulator is leaking at higher fuel pressure.I am running 580cc injectors and walbro 255lph pump,and a b&m fuel regulator modifier.I have noticed time to time that the gauge on the pressure fluctuates from time to time about 3-4 lbs not all the time tho.I opened up the regulator yesterday to see if it had any rips in the diaphram ,and it looked good,except i noticed theres was a bit of fuel inside of the back part of the diaphram.Im not sure.I checked it and it does rise when its disconected from vaccum,but wheter or not its leaking under higher loads im not sure.What is the lb per boost rate for fuel pressure.Sorry this is so long just trying to explain it good.Thanks for any help peace teddy from indiana.Any other guys from indiana on here???holla.
I used to live in Warsaw. Its its not Detroit muscle then you are pretty much out of luck for support. Looking in Chicago would be your best bet.
Thanks for at least writing something lol.
