I'm running a Motec ecu on my GT86 with 4 lambda's (one per header) and its very clear just how bad the intake and exhaust paths are and the amount of difference required. Its not a constant offset either, amounts cross over. If you measure each intake runner and exhaust runner length they all have a different total overall tuned length so it's not surprising at all.

When will pricing and completion date be confirmed on this?
