My A/F gauge reads .84-.85 at WOT under boost, but that's what it read when the engine wasn't seeing boost at WOT, is it possible that my gauge just reads low? My setup is stock injectors with sfmu with largest disk and dark spring, and at 5-5.5 pounds FP was 70-75 psi(if i remember correctly that's about right or no?) Idle FP is set at 45 psi just trying to get a general consensus on my situation. Any opinions will be helpful TIA btw, will max FP be effected by raising or lowering FP at idle?

narrow band gauges are worthless, dont use one for tuning, use you a egt gauge and get a wideband.

i dont think lowering or raising your idle FP will affect your max FP under boost.
