The leaded fuel I was using was "LL100" av gas. LL stands for "low-lead," supposedly, but I have been to that that is a mis-nomer; that LL100 has a LOT of lead in it!
I am trying to set up the A/F ratio in a boosted application and detonation is my nemesis; it will KILL my engine, especially if it happens under boost.
What do you suggest I do, to get a reading when using 15 pounds of boost; no-lead racing gas? That stuff is like GOLD...
Is that my only option? My engine has an alcohol spray (Snowperformance Boost Cooler) and an air-to-air intercooler of an appropriate size.
