Pretty much what I wrote above. There's probably a small bump in power, but otherwise I can't ever have a MAF failure. 
The throttle would be pretty easy to tweak. Is your car 6mt or auto? I haven't noticed any real 'lag' with the 6mt, but I think a lot of it comes from the custom tune. |
6MT. I perceive the throttle to have a delay when first applied.
Could this be the throttle curve you mentioned?
Have you tested your tune on other cars? Did you raise the rev limit slightly? (can't recall if it was yourself or someone else testing this)
