But what do the really big guys use (I'm talking 1000+hp)? AEM or Motec, right?

 

I don't know any Honduh guy running Motec. I've seen a few 800+ cars on AEM, but dyno tuning an 800 whp FWD is freaking difficult and most stuff around or past that power figure gets the rest of it's tuning on the track. Those guys rarely rarely rarely let other people see their dyno sheets, anyway, since they are usually sponsored race teams.
