I tried stage1, but was disappointed in drivability (boost came on waaay too quickly for no reason... even with the stock throttle mapping) and power compared to my JB4. Things got even better with 'auto-learning' (map 5) on the JB4, while I waited on Cobb to release a stage2 map...
I'm wondering how stage2 compares. I'll most likely flash it tonight, but I was hoping for some information to hold me over.
I ran the Cobb Stage 1 tune on my 135i, which was full bolt on. Now, running stage 2+ on the 1M full bolt on, is much smoother, and obviously more powerful. Yowzers!
