BM3 Race Tune - 480/500hp atw

[Race82]

Wanting recommendations/feedback for a respected BM3 tuner that can provide a custom BM3 tune for 2015 F82 M4 Racecar (catless with downpipes and charge pipes) that will work for enduro racing - not interested in a street or drag/roll racing tune.

Currently running OTS Stage 2 Map and very happy with the reliability and performance. Current dyno circa 335kw / 450hp at the wheels. Hoping to push to around 350kw /480hp (ideally 500hp would be great) on same fuel; 98 RON (which is 93 in USA I think?). is that even possible without E85 or pure turbos?

Needs to run reliably, with linear power whilst being mindful of not over stressing the car too far. I’ve had zero issues with OTS Stage 2 for past 2 years.

BM3 OTS 93 should be ~ 500whp btw not sure on why you dyno low. Mustang dyno?

Not sure, also using slicks for dyno runs which i don’t think helps?

Aussie dyno's (Dyno Dynamics etc) read a fair bit lower than US dynos.

My M4 Competition for example only made 245rwkw (330whp).

I suspect if you're going to want more (and reliable) power, E85 is going to be the only way you're going to do it short of changing the turbos.

From what i understand pure turbos can get you 600-750 hp depending on your fuel type and so on.
check out the pure turbos thread with the various cars and their power and what their supporting mods are and you will get the idea.
honestly your dyno must be running low because a BM3 tune with stock turbos has been shown to be over 500 hp to the wheels with ots stage 2 93 octane
