fuel trim ??
ok.. so i got a pcmforless tune.. i got new injectors, maf, plugs, wires, opti, coil, o2's. and i can't get the bank 2 fuel trim to come down at light throttle and/or idle. bumped the fuel pressure to 55psi and its stilll like 25-35% long term fuel trim but when i am getting on it it goes down to zero the rest of the way to redline.?? is that normal? its a 96..

bank two is the passenger side i am assuming? i cannot see or hear any leaks coming from that side.. the car drives much better with the new maf though.. i will just have to replace the header gasket also to see if thats it..
