[gorskined]

finally ironing out my fuel issues with the 3.0l row turbo runs and pulls great . i would love to reduce the deceleration popping sound. first i probably need to understand what causes that sound and hopefully there is a way to reduce it .

in a nut shell my 3.0l built to stock with stock P&C evergreen raptor mod k27 turbo long neck intercooler original Vacuum Limiter and a 964 bov fully adjustable wur. and a boost enrichment hold out controller currently set to 4800 rpms.
i believe i have my wur tweaked correctly i have good afr # idle about 14 with a nice afr curve that runs to mid 12s just before boost low boost high 11s and full boost low 11s.

When i let off the gas the afr# jump into the upper 14s low 15s. when under a load when i let off the gas i get the popping without a load i just get gurgling.
on a side note the car is a row but i have the timing set to American settings 5 deg advanced and 22 retarded. The row settings are tdc and 26deg retarded . i have not played with the setting other than at an idle and i didn't notice a difference. would this help with the popping ?

i would love to learn more about the popping and the variance in the timing between the row and the American. ..

Thanks in advance
