Hey everyone, here are my results from the dyno using a Dynapack.

Here was the 6psi Baseline.


here is the final run on 6psi after the tune was complete. this was after a good deal of heatsoak, so keep in mind that if we had done a cold run with this tune, it would have been at least another 10hp/10tq higher. it took me a bit to realise why i couldnt get rid of the dip in the beginning around 4000rpm's, but that is because i am using a p06 ecu that does not have control of the secondary butterflies. so when i did the initial install, i connected the vacuum line for the secondaries' diaphragm directly to the manifold. which means instead of them staying closed then opening around 4800-5k rpms, they are now controlled by manifold pressure instead of rpm. which means that the secondaries will be open at all times in boost. which equates to a loss in power in bottom end due to less efficiency of the manifold (runner length and diameter). it is definitely a noticible loss on the chart, portrayed by that nice large dip lol, but its really not that much of a difference compared to what it would be if the butterflies operated according to rpm. so here it is, final tune on 6psi in my 100% bone stock h23 heatsoaked and with the secondaries open at all times in boost:

looks good. gotta love the torque of the h23. and pics of the motor?

Your setup looks very nice! I can't wait to start getting parts to turbo my h23 5th gen Accord.

EDIT: you CAN add the function to your p06 to control the secondary butterflies. That's what I did with mine ...

Gotta love the torque numbers that come along with the H-series. Torque numbers are just as high as the whp numbers lol Looks good

What turbo are you running? Looks like the hot side is a bit too small by the way the torque drops so fast.

Yeah get a bigger snail for that
