Got some runs in last weekend and logged them on autotap and wasn't pleased with them. While staged I got the rpm's up a bit to launch and showed 2* knock off the bat, By the time I hit the big end I saw 5*. It ran consistant 13.40's @ 103.9 with a little spinning into 2nd (mods below) also it was around 80 and humind. It put down 343 RWHP on the dyno so it should trap better times than that. I also took my Rpm's and Map(kpa) and checked my timing to a stock table and the car was running stock timing .. How much timing will that much knock pull? Is it just a stroke of luck that it's being pulled to stock timing or did I loose my tuning? Thanks for your replies

 

get the LT4 knock module. My car was pulling up to 10 degrees with no evidence of knock. th KM got rid of all of it, now only see partial to 1 degree on occasion. $30 well spent
