Shell, Chevron, Sometimes Sunoco
It varies
I definitely noticed an improvement
But it's just inconsistent
I mean the best time I could get stock was 3.2
The best time I got on map 2 was 2.94
I just fee that the times are weak in general
I figured on a stock comp I would consistently do 3.0 on the street with 93
And with jb4 I would be in high 2s (like a 2.7) consistently ...
But I struggle
I should test some 60-130s
And quarter mile times
There is a track event next weekend so we shall see
I know the 0-60 is not the best barometer for quickness due to different variables (either way the car is fast) but I still think those times should be much lower for a 2019 M5 comp w jb4
I have Michelin Pilot sports from factory
I don't have ceramic breaks (maybe that's adding weight) ...
I dunno
Car definitely getting more boost
I will say that jb4 doesn't feel as smooth as stock
I sent terry maps immediately after install because car had the old firmware and through a drivetrain malfunction error
I installed new firmware and he said they looked good and to continue running on map 2
But again 2.94 is meh
