If currently running jb4 on map 2 (Injen evolution intake, downpipes, charge pipes) would one be able to flash the stock tune for the gts roar, burble and cel delete and simply keep the Jb4 on map 2?

Or am I better off JB4 map4 and flash stage 2 bootmod?
The reason why I have not wanted to flash stage 2 bootmod for 93 is because sometimes I will pump 5 gallons of e85 occasionally.

Thanks!
For the latter, run the BM3 Stage 2 E30 tune. Leaner AFR and more timing.

I thought about that as well my only worry was if in the event I am not near an E85 station and have to pump straight 93 how would the car run?

Right now with the jb4 I can switch back and forth between e30 and 93 without touching anything as it adjust to it on its own. Would the bm3 e30 allow that too?

BM3 is cloud based, so you must always initiate some type of internet connection first. From there you can work offline.

If your phone has “hotspot” functionality, then you’re fine either way.

Although flashing BM3 maps requires ~30 seconds. Not on the fly like the JB4.

Let me start off first by saying although you're adding E85 the Jb4 is not properly tuning AFR, Timing and Load Target for the extra octane. All you're doing is running boost which in these cars with a higher ambient temp is not going to go faster.

I can guarantee a BM3 STG1 E30 (30% of E85 ratio to 93) will outperform in all the areas any map you choose on the jb4 itself. The only neat feature I see of the jb4 maps is the custom map6 and valet map.

Bootmod3 now has 30 seconds map switches from 93 to E30 or Full E85 map. And they just released a sneak peek of their new development coming soon for Map Switching etc.

Map4 is stock map and wont let anything else talk to the car via OBD if connected so needs to be map0 and for at least 24hrs.
Recently heard of a few randoms cars B58, S55, S63TU having jb4 on map0 and their car would still overboost
