I think your reading way too much into this. My exhausts were never the same either. Their different lengths and have a crossover. I'm reading this thread off my phone so I couldn't make out your screen shot to well. Injector pulse width should be different. Cal 1 is the rear and runs hotter do it should have more fuel. Injector pulse width is done in percentage of available time to open the injector. We are talking maybe 20 milliseconds here. If cylinder one is 2.6% and cylinder two is 3.1% we are talking about 1/2% of 20 ms. You injectors probably aren't even matched to within 3%.
