Here is what we did. Test car was a 2003 6spd touring model.
The dyno was a dynojet. All pulls were done in 4th gear. And the ECU was reset in between each mod.

2 pulls each, these are the best results.

The tests were:

Dyno 1 = STOCK
Dyno 2 = Ported Lower Plenum
Dyno 3 = Ported Lower Plenum + JWT intake
Dyno 4 = Ported Lower Plenum + JWT intake + V5 Kinetix Plenum
Dyno 5 = Ported Lower Plenum + JWT intake + V5 Kinetix Plenum + Ported Throttle Body
Dyno 6 = Kinetix SSV + JWT intake + Ported Throttle Body

Dyno 1 STOCK we managed to pull 238HP/224TQ not bad base line
Dyno 2 241HP/228TQ
Dyno 3 244HP/226TQ
Dyno 4 243HP/229TQ
Dyno 5 244HP/229TQ Ported Throttle body did not do much
Dyno 6 235HP/221TQ As you see the SSV lost HP over the V5 and alot of TQ

Here are the dyno graphs
