Did you post another thread about the install or a DYI ?
where are you planning to get a tune ?
I may be, but its very well documented mod. The best description is of the Z4 on zpost who did the DIY, everything feels more angry and easily noticed more if you reset the throttle map.
For DIY I followed the Z4 manifold swap on zpost, I could append that great DIY with some tips for 128i. There are areas of surprise attached to the bottom of the manifold that require Torx 30 or to unclip the plastic lid of the box and be careful. I didnt disconnect the strut tower brace.
Step 1 is to find an X3(I got this one), x5, 530i, 330i or z4 3.0si manifold.
Step 2 is to take it apart, remove all sensors and DISA
Step 3 clean it & rinse it. Water & soap
Step 4 connect one DISA at a time. Turn on car and see that it closes when idle
Tune, lol 6mt is my tune
I dont see the need for one right now. I should dyno to see how bad that Dip is vs Xi or 328i, also to see if I need to change the intake from stock to Eurobox, AFE magnum or similar
I messaged some tuners and learning about what the x28i does with DISA.
