Hey did you finally swap to the newer style MAF? I actually managed to do it for my 94 corrado vr6. Exactly like you mentioned (took it off the vortex as well) how is it working for you?? I did it because of turbo upgrade and I wanted to use US C2 software..... unfortunately it's not working the way it supposed to for me, not sure why. Seems like there is a problem in the software for TPS sensor (doesn't matter is I use stock chip or turbo one) - so I am wondering am I the only one with this issue? When I have TPS connected the car bogs down part throttle (lean condition showing on AFR gauge)
