Not sure on the exact time frame that the dyno will be don for the N/A manifold, but it will be relatively soon.
The one for the F/I will be before the month's end.

If I remember correctly the FJ made the same power as the Taco but premium fuel was recommended because of emissions issues.
I read the output numbers recently. Not sure where? It might have even been posted in the Performance section? Kind of under the weather right now. Either way, the timing gets bumped up by the ECU on the higher octane. Just a tad and just enough to pick up a little more power. Nothing special, but true. What really is interesting, is that the '03-'04 1GR made more HP and TQ. About 10hp and 20tq.
If it weren't such a pita, it would be worth swapping some heads.
Also, these are just the first designs. I am quite positive, that if these do well, the desire to make refinements will be there.
If we don't have the desire to test things out, at all, how can we progress forward from where we are?
