Of course if you have an safc2 or other air/fuel controling device you can lean the massive 55% enrichment over 4500rpm's out to what ever you want. For example. If you tuned the 1g pump to 11:1 (same past values) you would net a max of 31lb/min airflow & 40lb/min airflow on the 2g pump.
Wait, i thought 2g's Ran at 33psi fuel pressure, stock... am i wrong? if so, let me know because i have my FPR set @ 33 psi... with a walbro 255hp pump, and a rewire...
