Changing Manifold/Uppipe... Remap Required?
 

I'm looking at swapping my current manifold (scoobysport equal length tubular) and uppipe... for an OEM unequal length ported manifold with a matched uppipe.

Will a remap be required? Obviously I understand that its not ideal, but will it be an urgent requirement?

97' STi with spec...

Forged 2ltr
VF22 Turbo
550 Injectors with FPR
3" turbo back decat exhaust
Apexi ECU (Bob Rawle Remapped)
Induction Kit blah blah...

Cheers ya'll :thumb:

Ye it will need a map tweak. Fueling etc. I would'nt say urgent as long as its driven off boost.
