What kind of awhp should I expect from a BM3 Stage 2 92 Octane + Catless DP?

Installing soon.
I know it's all relative but I'm just curious what everyone thinks.

Over all 340hp maybe less.

Stock turbo and HPFP seem to be good for around 380-400whp. If you're pumping grade 92, you should not run the Stage 2 93 map.

You should expect somewhere near 380 if you have the catless downpipe and intercooler.

Don't tune it without replacing the chargepipe. Don't go to Stage 2 without an upgraded intercooler.

I have the CTS turbo ChargePipe . I’ll be running stage 2 BM3 91 octane with catless downpipe but no intercooler upgrade yet.

It'll boogie!

I recommend staying with stage 1 on stock intercooler, temps will go up and ECU will lower ignition timing to protect your engine. You are overworking the car for very little reward

False information ...

Adds around 100hp over stock, would recommend FBO before going Stage 2 tune and one step colder plugs gapped tighter after you go Stage 2 if you are getting timing issues. Charge pipe is a big must if you go anything above stock as its only time before you hear a kaboom under the hood!

^im All bolt on with stock turbo running that tune. I personally think it's less than 400hp but I never put her on the dyno so maybe it is.

That would be 339 to the wheels, I presume!
If so, then that’s 400hp at the crank if you consider about 15% drivetrain loss.
Hard to estimate drivetrain losses but it sounds like 12-15% for RWD and 18-25% for AWD is appropriate

That's not a good run, something is wrong. You should be getting close to 380 to the wheels
