Do i really need to tune my ECU for my upgrade?
 

i had mod. my FD, bigger radiator, FMIC, twin power added, hks twin air filter, light weight wheel, exedy clutch. do i have to mod. my ecu for my 7 or i can use PFC with feed boost controller to mod my ECU? or i have to mod. my ECU seperately?


thanks

um the power fc replaces the stock ecu?

If all you have is an intake/IC and an ignition amp you should be ok with stock computer if you keep the boost below fuel cut.

Lots on info on this in old threads. Same goes for the PFC as an ECU upgrade.
