Does anyone experience torque down at 3k〜4k rpm like an flat spot of torque curve with this MAF less tune. Is this because I use the IAT from the stock MAF? or because of DISA valve open timing?
My car details: AFE intake + AA headers + LAPTORR exhaust. Currently canceling the O2 feedback but I experienced last time before canceling O2.

I had flat spots in the rev range that was due to slow disa valves. They are not serviceable but it can be done. I opened the disas and soldered the connections cleaned out the oil and plastic welded it all back together.

Does such a tune exist for the 325i N53? I got a 3 stage intake fitted and I'd like to put the 330i base map on it without going to a tuner.

Does anyone know where to check the MSV80 zb number for the car? For example E92 328i WB33 MSV80 zb number, E92 330i WB51 MSV80 zb number? For MSV70 you can find the numebr on realoem but for MSV 80 I can't find it.

Yes but that costs 600+ euros, admittedly it is an actual tune and not a base map.

For me, if a free base map exists like is shown for the N52, I'd much rather go that route.
