Hey guys I have an 03 wrx with el headers, uppipe, duel boost controllers, cold air intake, forge recerculating valve, gutted down pipe, 3 inch exhaust and tgv delete with a stage 2 tune. I'm looking to get a wideband O2 sensor setup on my car. I just need some advice on where to get one from and how far after the turbo to put it. I'm looking to get it for tuning reasons, my tuner prefers the wideband.
12 or 16 inches from the turbo and technically you can just relocate the oem front O2 sensor from the header to the downpipe because it is actually wideband. Will need a tune tho.
