Hi everyone,
I was just wondering how safe is it to run race gas tune bm3 ( stage 2 race gas) with stock HPFP on PS2 and FBO?
I’m worried about the car getting too lean because of OEM HPFP.

What does BM3 say on the description? I'm sure that most of the standard hybrid turbo maps are ok for pump, it's only when dealing with ethanol mixes where the fuel is less energy dense (thus requiring more fuel) when you start to run into issues.

Should be fine. Ultimately the gas quality will determine if your HPFP will crash or not. If you've logged before and your car was fine then switching to PS2 turbo from stock turbo shouldn't change anything. Your bottleneck is the HPFP though. Why would you go PS2 without upgrading HPFP?

I think there is no standard Hybrid turbo map, I’m just flashing standard turbo OTS map.

I thought for sure BM3 has 2H (for hybrid turbo) maps to be used with the stock fuel pump.

I believe they replaced that map with stage 2+ e30 and stage2+ race gas maps.

How are the spooling characteristics of the PS2 compared to stock turbo?
I'm fbo plus dorch stage 1.. thanks

It’s Definitely different, driving around on comfort, kinda Sluggish in slow speed, but if you’re little aggressive on the throttle you wouldn’t feel a thing and the car picks up nice.
Keep it in sport and wouldn’t notice it much.

Turbo lag is Obvious when you floor it at 3k or so comparing to stock turbo. You don’t have the Instant hit,But once is comes on it’s worth it

Thanks.. rarely drive in comfort anyway.
How the stock turbo maxs out around 5.5/ 6 k
Is a little annoying.
