Unfortunately the ECU is from a couple of years back and at this stage I don't have the money to upgrade it
I do plan on getting a full standalone IF I end up doing cams, which I plan to

Does anyone know exactly what ram/velocity tubes are? Apparently they speed up the air and are good for NA's

With a center mounted TB, wouldn't the middle runners get more air than the side ones?

I would go ITB, but I don't think there is any way to tune them with just piggyback is there?
And really I am already stretching the budget quite a bit (engine has been rebuilt, ported heads etc)
