How long have you been using the 50/50 mix? What do your logs show as compared to straight 93? You should have noted a significant increase in power in MAP 7 with the 50/50, am I correct?
Log MAP7 3 times for an average - save the data for comparison later. (save the csv files)
the Torco is worth a try in your case... I'm curious to see the change in a MAP 7 log csv ... (also, do u have the e85 harness for ur Jb4 since u do not have methanol injection?)

I have dp,cp and intake with jb4 but I don't have fmic. Map7 with 50/50 mix of 93/103 is a big difference from map2 or 5. Don't have Meth yet but that is next and believe it or not I still have not logged :-( lol but I will soon. Everything has been butt dyno so far but I do have a sensitive butt :-). I ordered 6 bottles and will test it out and compare it with 103 octane.
