So its time to replace or update the air flow sensor in my M5. I am wondering with my car what the best option will be. I have a S38 stroker and I need some advice on the best route to take. I have looked at the Miller Performance ( MAF and the Split Second Kits ( and from what I can see it looks like the Split Second kits offer more fine tuning capabilities, manually or via laptop. Any input is greatly appreciated!

I am also trying to to determine what the costs involved will be and if it something I should just hand off to my mechanic to handle.
