When my mods were AFE intake, ported IM/TB, and Borla catless X with S-type NPP (stock exhaust manifolds and primary cats), I would get lots of good gurgling snap crackle pops on decel when going in or out of DFCO.
I added ARH midlengths with hi flow cats, adjust the tune slightly for the changes but nothing that would affect decel MAF area or DFCO. When looking at my logs everything looks great. DFCO is still kicking in like it should and everything is almost identical from a log standpoint prior to the ARH install.
BUT, the big BUT, I've lost the real good pops and crackles from the exhaust. I get louder burbles but it doesn't pop like it used to and I really loved that sound. I was actually hoping it would pop and crackle even more. I tried adding some fuel in the VVE area on decel, but it just started to throw my LTRFT's off (started going too far negative in that area).
MAF, MAP, Timing, Fueling etc all match up prior to the headers in the logs, but the pops are gone. It used to pop real nice when cold, but even that isn't the case anymore. Is this something I just have to accept that I lost, or is there another way to bring them back on the Gen V stuff?
Thanks
