E30 Stage 2 is 20PSI & 15 degrees of timing
E30 Stage 2 plus is 23PSI & 14 degrees of Timing

With the 91 octane custom tune would be interested in the values?

you have the numbers for 93 oct? Also the GTS tune thru BM3 targets 10-15 deg without water injection? That seems a bit pushy. I was thinking of trying the GTS tune for the lower tq curve and better tq curve with the hp curve.... now not so sure

It's definitely iffy because other parts of town there isn't many stations.

So you think it's definitely more than 3% gains from Stage 2 91? I figured maybe protuningfreaks was giving a very conservative number.

I feel like E30 is definitely more than 3% WHP and more torque. I definitely don't feel a difference between 91 stage 2 and E30 tune below 3500 RPM. 3500-5000 RPM is where there is a huge difference, IMO.



Not Apples to Apples but here is a dyno for JB4 E30 running on higher boost

Flashed OTS E30 tonight. Mixed 5.6 gallons of E85 with the remainder ACN91. Did some test pulls after the fuel had a chance to mix and noticed the engine was pulling timing. I added an additional 0.9 gallons (6.5 total) of E85 and things were happy. I calculated that I’m at approximately E41.

I’m going to continue with this setup until I get a fuel fuel sensor installed.

Any recommendations on a kit?

Has anyone logged stock tune pull? What's stock timing?
