I had the opportunity to get the EVO X on the dyno a few weeks ago and do a tune on MS109 fuel. I am just now getting the opportunity to post about it .

The car now has:

AMS FMIC
AMS Turbo-back exhaust (no cat)
AMS Prototype o2 housing
AMS Upper intercooler pipe
AMS Turbo inlet/maf pipe
AMS MBC

---------------------------------------------------------
No boost or AFR curves available. You will just have to trust me.

29psi falling to 20
Mid to high 11's throughout the RPM band.

Tuning is being done with the stock ecu and ECUTeK.

I am pretty sure our BOV was leaking a little bit when it made these numbers. I have been meaning to get it back on the dyno to check it out, but we have been swamped!

Car is very quick with these mods on it. I HAD TO check the tune on the street real quick and I was suprised by the way the torque comes in and how well the power holds for having so few modifications.

Anyways, here is the chart you are looking for:

nice power increase. Though its still jittery towards the end...

I wonder how it would do on pumpgas.

Probably wouldn't do anywhere near the same boost.

Good gains though.

thanks for sharing!

I wonder if the jitter that you see at the end may be caused by the variable timing.

It looks a lot like it. It looks similar to the top end of a turbocharged B16/B18, although VTEC dyno's are a bit more erratic. Curious what they are going to do to sort this out.
