Trying to figure out why I can't go any faster and/or Increase Boost or Timing, my Combo is in my sig., now the Problem that I'm having is that ANYTHING After 22-23#'s of boost and 23/21 timing I get Knock. My O2's are at 790-800 at the TOP of Third, and I've VERIFIED Fuel Delivery at 68-70PSI during my passes. All passes are Smooth, and pull decent, and I always Gain ~22.5 - 23mph from 1/8th to 1/4. My Initial is set at the 12:00 position, and my Controller is on 8. I use ONLY 93 Octane, and My fuel is at 142 overall(+10.9%), if I Increase the fuel my o2 numbers go Up and I SLOW DOWN, if I increase the Initial and up the Alc., it floods it with Alc., and I slow down. I HAVE tried backing OFF the Alc., and UPPING the Fuel, but that just seems to get me More Knock, so I am Apparently STUCK at this 22-23# and 23/21 timing Threshold. This is with a Turbotweak chip for a Stock Turbo, but the Turbo is the One and Only change I've made to my Combo, still have the Bone Stock Downpipe and Intercooler so I thinking I can still use the same chip(just increasing fuel)....I've attached the PL files if anyone wants to take a GANDER, on the PL Files where you see the KNOCK is where I TRIED to Increase the Boost! All the Temps during these passes were in the Low 50's, and the track is at Sea level, Ethanol is Fresh VP...
