Jason,
You are right, I am talking about mostly stock engines.
When you start swapping cams and futzing with head/pistons/etc I don't
pretend to know what will make your engine happy. But with the stock E30
M20B25 engine, after market throttle body is not it. 
I also read in one of the auto publications the same verdict on
bad-ass-throttle bodies for non-blown VW engines.

Oh, but his chip was custom burned for his car, not yours. 
Even if you had a better engine, the guy's custom-built chip was not tuned
for your engine and may not have been able to wake up all of your engine's
horses.
