Greg, is there a table where you can change the load at which the ecu changes from closed to open loop? I feel like at lowish rpms (2000-2500) the car is sluggish because the ecu is trying to keep thing stoich. Then it rockets forward at 2500 as the ecu finally decides to add fuel.

I've been able to combat a bit of this using the fuel map, but it seems like the wrong way to do it. Either the maf scaling at that range needs tweaking or the closed loop threshold needs to be lower.
