I'm having issues with this Stillen SC setup. But I'm not sure why. My issues seem isolated to Bank 2 (Cylinder 2, 4 & 6). I have the Stillen Intake Manifold, so air is shared going in... but my AFRs on Bank 2 are giving me nothing but grief. Replaced AFR sensor Upstream & O2 Sensor Downstream. No change.
Recently blew out the Bank 2 Cat. Even after replacing the O2 Sensor, ECUTek is now no longer seeing anything for either Heater Circuit, Bank 1 or 2 (stuck on 0.28v).
In addition I'm getting a really bad jerking when in low RPM & under load, say cruising uphill.
Photos attached of the AFR readings I'm getting, this was just relatively cold-start and idle for a short while. This is driving me absolutely nuts. Can't finish tuning the damn thing till I figure this out. I'm starting to wonder if I have shitty injectors... but it seems weird that it's only limited to just one bank?
