I know the basics i just wanted to clarify if i brake-boost @ 2000rpm in 2th manually, I should let the car shift from 2 to 3 and over or manually shift from 3 and over before redline?

I would just let the car do its thing. Once you get a few runs you can experiment. I have a fair amount of passes with the 335d and leave in first and let the car shift when it wants.

You leave in first gear ?
Manually and let the car do its thing after ?

[335dsleeper]

Yup

I do 2nd gear manual mode 2400 RPM launches and let the car shift itself. I found 1st gear kept spinning the tires for me, and I also aired my all seasons down to 28psi.

Street tires should be left at the manufactures spec. Street tires are not designed for a large pressure variations. The side wall, tire compound and tread design are not intended to be run lower than manufactures specs.

Manipulating street tire pressure is just asking for trouble. Lower pressure on a street tire does nothing for traction, but increase tire wear and reduces contact patch in the center of the tire. The lower the profile, the more damage lowering pressure will do.

Street tires and drag radials/ slicks respond totally different to lower air pressure. It's completely different.

You should avoid the water box. Spining a street tire does nothing more than make them greasy.

Leave your tire pressures alone, as long as they're properly inflated and drive around the water box and should be able to leave hard enough to get a good et.

On my way to the strip, there is an abandoned other strip which I went and try 1/4 function on my bmwps electronic steering wheel and I got a poor 3 sec 60ft
13.9 103 mph ?
Second run 14.02 104mph

THAT IS NOT official ( numbers from my steering wheel, Michelin pss 6/32, outside temp. 2 degree Celsius)

[335dsleeper]

Yea, I wouldn't pay any mind to that. Also, don't concern yourself with the 60ft yet.

Why would you expect 108-109? You have all your emissions in place and not running water injection.

My car went 107 on the stage 2+ tune alone.

[powellrm]

With the emissions in place looks good to me

Mess with 2nd gear launch and see if short shifting will pick up any MPH.

Not bad.

Here's a quick comparison. But this guy had slicks, JBD, and meth.

Can you weigh the car?

Don't forget to let her cool down. She's not going to like hot lapping.
