WebJan 14, 2016 · thedjfx 🎙️. The former (deep) is ambiguous and can mean any ratio or threshold, IMO. Low ratio vs high threshold only means how much (or little) the signal will get compressed versus at what level this compression ratio (the processor) should be triggered. That is, ratio and threshold are two different parameters. Yes, exactly. WebApr 15, 2013 · Higher comp improves off boost driving and spool time but those motors really dont have issues on low comp and spooling turbos. I dont see a need to go higher than 10.5:1 for boost. 9-10:1 is fine with ls motors. So many guys running truck take outs at well over 600 whp at 9.5-10.0:1 comp just fine.
