Which exhaust do you have? Midpipe + Axleback + Downpipe? Or just Midpipe + Axleback?

Nice dyno, thanks for posting. How long have you had the v2? has the v2 been flawless? No check engine light? Hows the power delivery and drivability?

Haven't had it for too long, changed from V1. So far so good.

dyno

what type of dyno where those numbers run on - I have the exact same mods except MPE exhaust - based on factory claimed numbers those seem really high = I will be tracking our M240 this sunday - Last year with just the tune we did a 12.1 at 109 1/4 with good air -- We are hoping for a high 11 this year - will post slip

Factory claimed is way off according to Dinan. They have it measured at 381 hp and 401 for torque.

The BMW factory numbers are closer to WHP and WTQ than crank numbers.

2016 Mini was the same - factory HP 189 Dyno 188.03 WHP factoy TQ 207 WTQ 229.36

I actually have no idea what type of dyno it was on, but I will find out.

Less explosive torque, smoother.

Yes. It feels more like the Dinan Sport set on Sport+ (+3 PSI), than the v1 stage 1.

As posted earlier we have the exact same mods - consistently run low 12 and have had 2 runs in the high 11 - trap speed between 113 and 115 - 60 ft between 1.88 and 1.95 - Our biggest problem is at the line - even with launch control the car had turbo lag hence the crappy 60 ft - we are hoping the Dinan Stage 2 addresses this problem - which should get the car mid 11 in good air - one thing for sure it will really heat soak and does not do well in high DA unless really cooled down - I mean Ice and a fan.

What do you mean by high DA? High density air?

DA is a combination of Altitude - Humidity and Air Temp - Turbo cars are really affected by all three - and will experience Heat Soak - One solution is a bigger more efficient inter cooler

That understand, but wondering specifically what DA stands for. Is it a acronym?

Edit: Just found out. Dynamic Altitude.
