23 M550 + JB4 Map 2 = 11.26

100% stock with JB4 Map 2. Foot brake, no LC, DSC off. Seems pretty quick.

I expect you will put down the same times if not faster on map 1 from experience.

That is quick. My best with BM3 OTS Stage 1 93 is 11.17@127. I went last week and couldn't beat 11.25@126. This is with xHP stage 3 on a prepped surface.

What is a little confusing to me is my 0-100 on those runs was 3.5s which is around 3.3s 0-60. That's quicker than above and my 60 foot is the same and mph is higher yet no faster over the quarter. And you DA is much worse.

More power is the answer :-)

Assuming you are using pump fuel, I consistently saw a fairly large degree of timing pulled from logs at +6 lbs.

On map 1 +4lbs boost the timing came back up and the car was quicker.

I’ve been consistently using exxon 93 oct. I’ll try stage one and record the results. Thanks.
