PTUNING GT3076R 9 PSI Preliminary 93 Pump Gas Tune
 

We've had a lot of folks ask us what our upcoming turbo system will make at higher boost levels on pump gas. Here is a preliminary 9 psi tune. By preliminary, we mean we didn't spend too much time dabbling with optimizing the tune since we went with WMI shortly after. We'll likely revisit the 8, 9, and 10 psi numbers once we start our local install/tunes for customers who have pre-ordered our set-up.

Note that the tune is knock limited on the 93 pump gas and cannot be tuned for MBT at the power levels that we are at.

Also, for reference, please keep in mind that our Dyno Dynamics Dyno reads 10-12% lower than a Dynojet.....something that a lot of the Vortech and Innovate SC guys will attest to. We'll let you guys do your own math though to figure out what we'd likely be putting down on a Dynojet.

Which turbo is that again?
Edit: lol its in the title

:bonk:

I believe its in the title gt3076R
Any other modification besides the turbo kit?

I'm glad to see people are testing real gas and not california water.

The only mod we have is a 3" V-band exhaust system. Something we highly recommended with any FI application for the FR-S/BRZ.

Other required supporting mods:
Larger FIC port injectors
4 Bar MAP sensor
Exedy Stage 1 clutch

We're running the stock (untouched) fuel pump/assembly.

You say you're det limited, how much advance are you able to run on the top line?

I don't remember the exact numbers off the top of my head, but the timing values are disproportionally lower as the boost goes from 4 psi (MBT tuneable) to 9 psi.

Adding WMI to the mix as allows us to add 3-4 degrees of timing at the same boost levels, thereby allowing us to reach MBT at these mid boost levels.

Fair enough, I like to keep my spark angles above 12 degrees to avoid high EGT's. Just wondering what kind of territory this power level is in on 93 aki fuel.

Can't see the chart its blocked here in the Stan. what'd it make?

318.7 whp
257.1 wtq

.82 A/R?

Not only does it allow more timing but you are able to bump up the boost like 30% more? or 50% more? Untill you are knock limited again.
