I don't know if the intercooler offers much benefit yet as I haven't tested it personally. It's interesting that the "worlds fastest" Stinger (ours at ~120mph) is running stock downpipes, stock exhaust, and the factory intercooler.
Of all the mods out the primary downpipes probably boost torque dramatically (good for AWD vehicles launching), and may open up a little top end power. Waiting for someone to do solid back to back testing.
In terms of tuning with downpipes the v6 maps work well, but like all areas of development, we'll continue working with customers for improvement as we see opportunities. Also be aware installing downpipes is highly illegal inside the USA so if you're going to violate federal law probably not a bright idea to share that on public discussion forums.
JB4 has the fastest stinger? Or fastest trap times but slower 1/4 mile times? Last I checked even with meth the jb4 had a slower 1/4 mile than 2 others. Seems like a but of missinformstion fo the uninformed Terry.
