Yes, but I couldn't tell you how much. I wouldn't personally worry about it, and just code everything to 030. Unless you have the resources to test everything down to the nth degree (dyno, gas analyser, ECU rig, HRC flywheel and stator, AVGAS, etc., etc., etc.) it's just not worth worrying about.

That's a strong, and safe, MC28! You're going to lop a little off that with an airbox, but honestly, it's really not worth worrying about different cards. 030 is the way to go in almost every scenario we've ever run.
