I guess we have conflicting results then.

I use hp/tork interchangeably.   I understand that hp is just tork x 
RPM.  3% more hp is going to be 3% more tork and vice versa.

_I_ would put money on the bet that an EFI-equipped 5KCSTQ would be 
faster if it had the same turbo/IC/etc as those other fast 5KCSTQs.

Since I did the 3" exhaust first, and then the EFI, I can comment on 
that.   I feel that the 3" exhaust got me about the same amount of 
performance improvement as the EFI.   They were additive too, mostly.  
Man, I _want_ a bigger turbo and a header!

Lets see, if I did the EFI only without the 3" exhaust, then maybe you 
would be right in that the 3" exhaust got me more hp over the basic car's 
162hp.

I figure its all a package though.   I can get a few small improvements 
from little tweeks here and there, but the big bang will come from 
combining everything optimally.   That is _very_ tough to do well.   I'm 
not there yet by any means.
