More or Less fuel pressure for hot weather (LT1)???
I have always ran best around 38 psi on my setup. My question is, in hot weather days should you go lean or rich to get best performance?

In general I have heard from a few sources, that LT1s run better with a slight reduction in fuel pressure....This seems to be opposite of the logical reasoning of higher fuel pressure and a better spray pattern, but just hearsay. The ECM should compensate for hot weather. Although, the true test would be a few dyno runs or runs down the street with some form of monitoring the performance (G-Tech). 94's had sequential port injection, and I would believe the ecm would simply reduce the pulse of the injector and leave you close to the optimal setting.
Just my thoughts,
