BM3 Stage 2 F80 M3 vs Stage 1

t111mmy · 07-31-2019, 09:35 PM

I have F80 M3 ZCP with vrsf downpipe + AA midpipe + BMS charge-pipe and tuned with Bootmod3 Stage 2 93 octane AGG , I like the power of the car but a bit concern about the crank hub issue as more power to crank would spin the crunk hub as others who do same tune. My question here what would you advise me to do , I have thinking of getting stage 1 tune or cs tune to the car or stay with stage 2? Which is better for a daily use , of course after tune there is more risk but should I go with stage 1 or it’s all the same?
Any recommendations?

Reliability of the car after tune is not grantee of course but at least looking for the best choice over all!

I have the same setup right now. And I was also thinking of going with a Stage 1 tune instead of the stage 2. But after trying to research reasons for SCH, there's nothing that I've found super conclusive. Seems like every variation DCT/ Manual, tuned/stock, can potentially spin their hubs. My conclusion is I'll probably end up doing Max PSI Keyed Crank Kit for piece of mind.

Not all that much change between S1 and S2 so I doubt S2 is really going to increase your chances of spinning your crank hub.

everything "can" spin. Its about probabilities. The more power the higher probability. Nay sayers are fooling themselves.

i am stage 1. Its plenty for me on the road. almost even unusable here in CT.

I cant see opening a can of worms to add dp and the associated PITA that come along with it. Nor the need to increase odds of crank hub issues. For what ?? another 20hp on a 500hp car. Seems like an easy choice to me. Was never even a thought to go to stage 2.

We are running the E30 map without any issues. If you like the power of the stage 2, i would keep it
