1/2 mile run with bootmod3

Wanted to share my 1/2 mile event results
Best run with 30mph roll 157.3 mph in half mile.
Standing 1/2 mile 153.9mph
Best 1/4 mile during half mile 11.12 126mph

Running bootmod3 stage 1 93 octane map.

Car is stock 2018 m5 non competition model

New tires 4s and plugs changed by dealer recently.

Wonder why my car is so slow, was expecting 10.7 1/4 mile run.

Launches absolutely fine with launch control.

Had jb4 before this had very similar results with map 2. Had racechip before that similar results also.
Sold all that for bootmod3 and still no improvement.
Very disappointed .
Maybe something wrong with my car, specifically.

What was your 0-60? I'm not sure BM3 has perfected the tune for the F90 yet....

i have only done 0-60 a couple of times. i get 3.31 2019 stock non comp
100-200 is 7.41. does not translate to 60-120 very well.

Very interesting. I'd flash stock and reflash the tune on. My base 2019 ran a 11.13 with 91 octane ... JB4 Map 3 I am well deep into the 10's with some E30. Some F90 don't respond well to tunes or piggybacks for some reason.

What fuel are you running ?

I was able to do this but let go off gas too quick. Slope is incorrect as all of my runs are at same place and it always changes to good or bad. I think if I don't release gas I should be able to do 165mph plus with 16.3 or less.

What year and month is your m5?
Mine was the very first one on the lot, March 2018.
Maybe production year and month might be the reason.

What are u referring too? I'm confused

Does manufacturing year or month affect the slope?

BMS did 162mph in theirs, JB4, intake, WMI kit. Factory exhaust and downpipes. Looks like 160mph before the WMI kit using race gas mix.

My my m5 model 2018 i think feb or March production date.

Maybe 2019 responds better to tuning.

Have u played with e85. I run 7 gals e85 with rest 93. If it's winter blend 70% ethanol I'm at e31-2 if it's normal 85% I'm at e36-7 so either way I'm safe n no issues with car. Can't run below e30 when pushing it.

I called some gas stations and their fuel here is best b/w 51 and 55% ethanol.

Want to know if something is wrong with my car, maybe not holding boost high enough maybe there is a leak, maybe ask bmw why car is slow.
I just can't get 1/4 mile better than 11.4 stock with perfect launch.
Tuned cant better than 11.1
