i am in the process of building an LS turbo for now it will just be stock motor on boost. eventually the plan is for pistons and rods and mild head work
i have been talking to some people.........i have a couple friends who own a shop they swear by aem, another friend whose opinion i greatly respect(he knows his ****) says hondata s200 with the boost option is plenty. he said that aem is overkill for what i plan on doing

Hondata s200
w/ boost option
full throttle shift & launch control

AEM EMS
w/ 3 bar map sensor
UEGO wideband 02

obviously a big difference in price i am just trying to see if i can justify spending an extra 800 bux for aem
