No other mods, stock 19's and rubber.

First two passes were consistent with both being 11.7 @ 123mph , and third/final pass a tad slower at 11.8 @ 122mph.

Boost reduction in 1st: 40%
Boost reduction in 2nd: 30%
Boost reduction in 3rd: 10%
Nice numbers. I assume DCT?

Do you know the DA for your runs?

I've often wondered what % of boost reduction would bring the BM3 OTS Stage 1 back to stock power levels. My guess is 20%.
Thanks! Yes, DCT.
Yup, DA was 1220

That's a great question. I thought I remember that 20% in 1st,2nd,3rd was equivalent to a linear CS map...???

It's funny cause my best run, which was my first, was the fastest with the LC launching at the default 4,000 rpm. I thought for sure, lowering it on the next two runs would have negate some wheel spin a tad. Oh well, that's racing
