right, fitted an AEM wideband lambda to the car recently (f7p turbo running standard management with a fastchips chip on it)

running uprated fuel pump
gt28rs
wossener low comps
fuel pressure regulated to just over 3 bar at idle with no vac on the reg
15psi
bosch 802 injector (R21 turbo ones, they are 802's right?)
pace chargecooler

results are bit sketchy as it goes some so hard to let her rip and watch the gauge at same time and i havent got it data logging yet so it was glimpses when i could on full chat

idle - up and down constantly in a loop between 14.3 and 15.6
full chat at full boost in all gears - 11.0 then climbs back to hold at 12.2 on the nose

opinions?

cheers folks

Ben
