I'll do some draggy pulls next week once my new tires go on. It's def not a sports car but highway rocket for sure.
When you did the stage 2 tune did they know you were installing the new catless down pipes? They told me if I installed them on the standard stage 1 or 2 tune the car would throw codes. Just wondering if when they installed the stage 2 tune they disabled the offending codes?? I have the stage 2 tune on order (not installed yet) and have the downpipes.
Stage 2 is only for cars with Catless DP. It's basically a more aggressive version of stage 1 because of less restrictive exhaust
Shouldn't be any codes if you install stage 1 then later do the DPs but you'll be leaving a bit of power on the table running stage 1 with DPs. Def don't run stage 2 without catless DPs.

Mo from DME Tuning suggested adding 1-2 gal of E85 to each full tank of gas, is that just to increase the octane count?
Yeah! E85 has an octane rating of 108 octane so adding that with 93 will bump it up theoretically assuming you're getting quality gas.

the only 93 octane gas near me (Cenex brand) contains 10% ethanol, is that acceptable for 93-tunes?

That's odd to hear because when I asked him last week about e85 he strongly recommended I stay away. I'll have to reach back out and get clarification

Perhaps he meant not using e85 straight?

Yeah you'll be fine. It's taken into consideration.

Mo from DME Tuning did Stage 1 on my '16 750 this am. The process was smooth and the car is indeed much livelier, with a definite shove in the back (did not even try full throttle).

Traction control. Hold the button down for a few seconds and it'll switch fully off. Def allows the car to actually use the new power. Nannies kick in and kill quite a bit of power when any wheel slip is sensed
