1. Why is the NA tranny so weak? Is it the gears and shafts, or maybe the case itself twisting.
2. How weak is the NA rear? Also, are open diffs less likely to break than lsd.
3. How does the ECU do the timing? More vacuum = more advance, boost = retard
How high can the stock ECU go ( boost wise) before it stops retarding, and freaks out?
Thanks for any answers.

2. dunno, 200-225?
3. it goes by rpm, and then by vacuum/ throttle position. it can only retard up to boost cut, after that it doesnt "see"

Ooops, I meant NA ecu. Can that 'see' boost?
