Turbo seems to be Lagging???

Car feels like it is bogging???

When I floor it from an idle at a stop sign my car feels like it is bogging for a second or two. When the power kicks in the car sets you back in your seat but it just feels like a dog at first. What could cause my car to run so rich at low RPM's and how can I correct this so I dont run to lean on the top end? I did a recall on my scanmaster and it said my 02's were at 777, 4 degreees knock at 20 MPH... Does this sound really bad? I have fuel pressure set to 48 psi static. Is this too high? Any help is greeatly appreciated, THANKS...

Lower the fuel pressure back to 45 psi. If you are getting any knock, your octane isn't high enough or your boost is too high for the octane. Turning up the FP to reduce knock with a thrasher is a no-no. It's not a good idea with any chip actually, because it doesn't solve the root cause of the problem, only treats a symptom.

If its still rich when the FP is turned back to 45 psi, look for a Header crack or crossover leak.

You said your O2s were 770. This indicates lean, not rich. How much boost are you running?

19#'s on 100 octane unleaded. The recall on the Scanmaster tells you your Highest knock count, lowest 02 reading and what MPH it happened at. Normally my 02 counts run betweeen 820-830 at WOT so I dont think I am running lean... Anyone else have suggestions??? THANKS

on a scan master around 780 02's are optimum

if your getting knock at 20 mph from a lauch i would think you have some falde knock which will retard the timing and make it fell real lazy.

might want to check for exaust hitting or for tv cable hitting the knock sensor
