I have not dynoed with anything other than a 50/50 mix.
Next weekend we are having a dyno day, and I plan on trying to do a few runs with water, standard off the shelf windshield washer fluid, and 50/50 again, each on injectors alone, and with the EZ. 7 runs, plus system purge after each swich. I don't know if I will be able to do all that. We are hoping for 50-60 trucks running that day.
Now, SOP says there is a little gain, as in I can feel it, but that is probably just added boost/more air at lower RPMs, which just means I am burning more fuel rather than puking it out the exhaust. With the system on, I am either climbing to or holding 14psi, or I am climbing from or holding 20. There is no 15-19 due to the rapid boost gain.
