IE 7.5 Flex Tune; Who’s running it?

[Hans]

Curious about your impressions. Is 50% to 100% E85 a significant difference in everyday driving, or mostly during WOT?

The difference in everyday driving would be your fuel economy.

on e85 with just an HPFP you end up with less power than e50. not an issue with an uncorked fuel system, but that's not what IE supports.

Yep; aware of the mpg hit that E85 brings.

I like the flexibility of not needing to measure and mix, and fill up with just 93 when I want.

what are you curious about then?

Yeah; maybe I wasn’t clear enough. The dreaded ‘is it worth it’ question. Currently running Stage 2 and looking for more umph with the least amount of fuss. I have the IE software, so it’s a hardware install only for me.

Curious what’s peoples’ butt dynos have been telling them, any bugs or challenges, etc.

And I already have the HPFP installed.

And I just found the other thread where you two were posting; good info. Your e50 comment makes a little more sense now with that context.

Do what your lords at IE recommend.
