Helix IC installed

I am in the Bay Area, CA, home of the un-finest faux 91 octane.

My mods are PROcede CANBUS, catless DPs, DCI, and now a Helix IC.

I was running a Stage II map w/UT set to 76%. I've just bumped that up to 79% to see if it still feels strong.

So far, so good. It didn't get too hot today and I think I need to drive a little more to educate the ECU, but think I can do a full Stage II with the upgraded FMIC.

Has anyone else in the 91 octane zone w/the same mods tried a full Stage II (80% UT) or a de-tuned Stage III with good results?
