My experience of a used £30 JB+ on a 2023 M240i X-Drivei
I have to say I'm impressed.
JB+ set to default position of 3 O'clock....supposedly giving an extra 3.5 PSI of boost. 99 Octane UK petrol 15 stone driver. 12 stone passenger. 75F Flat road. No wind. Absolutely no other mods. 3.51 seconds. PS...Rollout is cheating and not used when testing cars in the UK. |
