This wasn't done in need of any performance advantage. The +20s were the only known good injectors i had. The A1000 I had kicking around as well. As addressing fuel washing is the goal, The O2 sensor is being replaced as well. Thanks for the web link, that's going to be perma-booked.
Edit: Holy jeebus! Dropping from 55 to 40psi only gets me within 3pph, or 30cc/min, of the stock 33s. Yeah this sounds more and more like a REALLY temporary band-aid. I am a huge fan of Shel's cals, just a matter of time saving those nickels.
