all I have to say is..... WOW..... I went from a JL 3# to a JL 6# and my first reaction was "HOLY SH*# I better put on my seat belt!" I was kinda worried at first and I listened for any pinging at all on the second run. It held up just fine till about 95 at WOT as soon as I heard it I let off, I kept looking at my AutoMeter gauge and it read 16LBS! Wow what a feeling 3 lbs makes! Tomorrow Im throwing in my Denso Iridium Spark Plugs to see if it helps with the very slight pinging i had. All I have to say is Johnny Thats a hell of a product you have there! At WOT the sound is remarkable. I'll let you know how things turn out after I get the Denso's in!
