which should i get and which give the best performance???

 

here we go again !!!

GO with the one you like most ! they both are great and extremely similar in performance !

 

I dont think they are simaler in performace at all Mike K switched from a AEM to A comptech and his numbers went from 1

182/131 with the AEM
181/136 with the Comptech gained alot from comptech from 4800rpms to 6000rpms

but to each there own

 

aem-beware of puddles
comptech-less prone to water damage (if you see the design you'd know)
aem-okay low/midrange, tops comptech on the top end by like 1hp
comptech-don't lose too much in the high end, low/midrange alot better
aem-noisy as hell
comptech-quiet as hell

i believe Austin on this board has the comptech vs. aem dyno sheet
it has the comptech label but it is Austin's type R.
