Was anyone in this thread able to run a 3.75 pulley on 93 octane with just the dw 400 pump and without adding a fuel additive?

I am. I just logged it this morning. I saw up to 4 deg timing added in the mid range but 2 taken out over 7000 rpm. It was running 14.5 deg advance before the shift.Was anyone in this thread able to run a 3.75 pulley on 93 octane with just the dw 400 pump and without adding a fuel additive?
How much boost are you making now?I am. I just logged it this morning. I saw up to 4 deg timing added in the mid range but 2 taken out over 7000 rpm. It was running 14.5 deg advance before the shift.
Just today I dropped to 3.625 and put a bottle of boostane in. Hopefully I can get a log tomorrow.
According to my ecoboost pp gauge it was making 14 psi with the 3.75. Should be +1 with the new pulley. However, these numbers seem high so I suspect 11 before and 12 now.How much boost are you making now?

Thanks for the info. I want to see a half a can with a full tank of gas. Just curious to see what it does as the whipple tune the timing is capped.Just following up with more logging/testing:
Yesterday, I saw up to 4 deg timing added in the mid range but 2 taken out over 7000 rpm. It was running 14.5 deg advance before the shift. That was 3.75 on 93.
Today, I ran the 3.625 pulley. I added half a bottle of boostane to half a tank of gas. It added 2 deg through the power range, then slacked off to adding 0.6 above 7200 rpm. Max timing at WOT was 18, dropping to 17 at the very top end.
To summarize, I dropped from 3.75 to 3.625 and added the equivalent of 1 bottle of boostane to a tank of gas. The result was that it added 2 deg timing. Ambient was about 15 deg hotter as well.
My plan is actually to test exactly that by doubling the gas in the tank. Hopefully I can get this done next week.Thanks for the info. I want to see a half a can with a full tank of gas. Just curious to see what it does as the whipple tune the timing is capped.
Awesome cant wait to see results. My thinking is if a half can/16oz does the job. Then there is no reason to waste it as it's not so cheap hahaMy plan is actually to test exactly that by doubling the gas in the tank. Hopefully I can get this done next week.
