ok I'm going insane with this car I've had it for 4 months and done nothing but work on it!! ( Never buying another Sr) lol. ok so anyways its a 240 with s15 Sr and it will run awesome one day wideband readings are good then next day wideband readings are all over the place from 10.0-15.0 back and forth back and forth.... I had my bov vented to air but then recirct it then it seemed to run pretty good for a couple days then today I tried turning my boost up and it didn't go over 5-6 psi and the wideband readings were insane again I've messed with fuel pressure and cleaned my maf... any ideas what the issue may be? my fuel pump has been acting funny and I also have a fuel cell and a Jim Wolfe tune with normal bolt ons.
