JB+ on G20 First Impressions
So I just installed a JB+ on my G20 330i yesterday and I've been driving it around local for a bit and my initial impressions are great. I feel that the smoothness has been much more refined, and the gears definitely feel like they pull smoother, mostly in the low rpm ranges. I did a few 20km/h to 100-110km/h pulls, and those definitely seemed quicker than before. I hope it's not a placebo, so I'll be testing it for the next few days and post again on it. I don't really know exactly how much HP/TQ I gained from this, but I feel like this little boost tuner made the car's throttle response what it should've been coming from factory.
I did not move the PSI dial beyond BMS factory settings.
