Maybe the +3 hp gains is because of the 91 octane. Maybe 93 would be diffrent? Anywhose this ecu tuning group is claiming stage 2 of there tune is 665whp with tune and with catless DownPipe. Another 70+hp they also want 2400 for tune.

Still debating with myself if should I install mine and dyno it. Just to have a second opinion. We have 93oct here in FL but to be honest if I were install it and not see a 35whp increment at the very least, I'd take it right out and dump it.

I put half tank of 100 Octane and half 91 tonight. It feels better...
I'm thinking maybe I'll try it since I already went and got it. I'm gonna try to squeeze 3 dyno runs in one visit. 1 bone stock with Comp Package, 2 Charcoal Filter delete, 3 with BMS on Prog 1 on 93oct. I'll post my results here as soon as I get them, but like I said, if this doesn't result in at least +35whp from stock I'll consider it a failure and remove it. Not worth it for insignificant gains.

I know for sure after installing the BMS you need to drive it 200 miles at least before doing dyno run. Adaptation is necessary for piggy back tune
Alright so that's 3 dynos in 2 visits then. The BMS dyno will be on the latter of the two visits.

@LSM

Can you notice other changes with the BMS tune? Especialy the exthaus note? I remember to my 335i with Vishnu piggyback. With the tuning the car had a slightly different, better, exthaust note. Some more "blobbs" when i close the throttle and so on. More agressiv.

Thx for a short info.
Lars
