so here is the deal i got a fully built ls fully tuned up to 20 psi .well i drive normally at around 15 psi.decided to crank it to 17 and see how it felt .and it felt pretty good then when i let off the gas my idle was around 1300 then went back to 1k.and my gauge was reading 18 on the vacuum and my greedy was at 91 92.i usually set at 22 and 99+ on my greedy and gauge.ive went threw all the lines nothing is off or cloged.my bov isnt as loud as it was either.and it still hold boost no leaking no spikeing.any advice wut to check will help kinda stumped on this one. thanx
