looking for someone to point me in the right direction as to how exactly to properly go about tuning decel/over-run pops/bangs/crackles.
i have an LZ9 v6 swapped 88 fiero i utilized the stock e67 ecu to run standalone with an equal length y pipe to 3" out (no cats, just a borla xr1). car already burbles on decel but it is a very dull muffled burble and im after more of a crisp little crackle. so far ive looked at quite a few posts on here to no avail. lots of contradictory stuff and or the access i have (in advanced mode) doesn't give me the same table options.
any help would be awesome
