Help the engine breathe

The first real modification to the engine has been to add a dual throttle body manifold I picked up from Andrew who never got to finish fitting it to his engine and to see what the difference was to response or performance.
A second throttle body was acquired and modified by removing the TPS and welding all auxiliary ports shut.
A hybrid link cable was commisioned through Maltech.com.au using an UZZ31 auto kickdown cable and cruise control cable and a mounting bracket modified to suit the second throttle body.
A pair of steel mesh pod filters have been fitted to finish the modification off.
After tuning and back to back comparisons, the second throttle body made more power and trque across the rev range and particularly higher in the rev range between 4500-6000rpm where it peaked up to 8kw higher!
