hi guys ive just bought a 89 300zx tt swb manual after months of searching it has an induction kit cat back exhaust and an se nissan boost upgrade running 14psi and putting out 350bhp and 365lbs per ft of torque. someone said i should chip it as se nissan retard the timing thus losing power is this correct and would i see a noticble difference?

 

thanks in advance

It may or may not have had the timing retarded, that will depend on whether the individual car needs it. If you buy a decent chip, there will be areas in the map which will have been retarded in order to get optimum performance, plus others where it will have been advances, fuelling changed etc etc, but you won't have the blanket change that is achieved by adjusting the CAS.

 

IMHO, for safety when running 1 bar then you should have an appropriate ECU map.

thanks andy
