While that can be true, all it takes is time to get the aftermarket ECU's performing like a stock in terms of driveability, with the time and money you've spent on this surely a bit more on tuning is no big deal. Map it well on the dyno and then spend couple of weekends tweaking the cold start, drive-ability and part throttle settings, make sure the conditions are different on each weekend.
I feel the drive-ability on my RB26 with lnik ECU is very good, tweaked the cold start a few times and now its perfect.
Will be great to see it running, good luck, make sure to keep us up to date.
