i'm using tufoil on my b16a...no problem so far...it makes ur engine rev more smooth...FC not much different...use it when u change ur oil...i'm using 3.7-4 liter of castrol magnatec with 1/2 bottle of tufoil...
I like to change to standalone ecu for my car, just like to ask, can I stick to my stock engine parts first, dont want to touch anything besides the standalone and need to know whats the max power limit...
