For comparison my Mission Performance Stage 2 on E30 with catted DP - made 463ish wheel one day on the dyno and just a tad over 470 wheel on another day.

I would expect roughly the same output from most all of the major flash tuners out there. Sure someone will push things beyond those numbers for the sake of the dyno or drags....but I think a reasonable and responsible approach that balances performance with daily driveability (and reliability) will net like numbers +/- a bit of course.

The engine at those levels was very healthy according to the logs.

Anyhoo hope this helps a bit...

chenry but you are using 91oct with E30, so i think 93oct with E30 should be a bit more than 470whp right?

Hi PL-M340i
I am mixing E85 with California 91 crap gas (the best we can get here at the pump) to get to E30. As I understand it octane at that point is roughly 93/94ish. I'm not sure at what point you reach diminishing returns by adding E85 to 93 octane from the pump. I suppose that depends on how aggressive a tune you are running.

I think most stage 2 tunes would be quite happy with 93 octane from the pump. I know Mission really only tunes for 91 & 93 (before they go custom) and by adding the E85 I'm simply attempting to get to something similar to 93 from the pump :-)

I'm not the expert on these things but hope this helped a bit :-)
