I miss the torque curve of my old 135i - peak torque came on at 1,300rpm. That was a fun daily. Wish the S58 could meet in the middle and had peak torque hit a little earlier.

TBH based on what your saying your driving style is it sounds like your not even really utilizing the stock power. You would’ve been a lot better served with an M240i or m340i or a Supra as the B58 has way better low down grunt which is what it sounds like your after. If you have the automatic transmission I would suggest driving in auto mode in the second or third setting. The kick down is very responsive and will always put you in the rpm range you need to spool up quickly and once cruising keep the rpm’s down for fuel economy.

Got it. This is where I would want to data log and check out things like throttle closures and timing corrections. Previous experience with installing a piggyback tune and pushing 2 to 3 more PSI of boost I was running into timing corrections due to the quality of the pump gas near me. Adding a little E cleaned those timing corrections up and it was felt in the butt dyno. I'm more than happy to experiment with this and report back but would need to go with the JB4 since it sounds like data logging with the racechip isn't a thing.

Has anyone done a dyno on map 5 (default map)? I’d be curious what the power gains are at for that map.

Just purchased one thru RGsport. I had no intension to modify... 3 months into ownership and it begins.... Looking forward to the install and power gains.

You are about to put me over the edge...

map 5 is about 3 PSI, expect ~45 whp and wtq

HI, i was wondering if maybe someone have some fiedback on the VR Tuned chip for M2 G87? I watched their videos on youtube, seems legit but what is the real dif between them (VR TUNED, dinan) and racechip GT5 black but the price?

Thanks in advance for your help.
