This Manifold has done what is says. Turned up 12V 362 turbo injectors and AFC mods on a 5 Speed. Lowered EGT by 75 degrees and spools at around 1550 Rpms about 200 Rpms faster than the stock Manifold. Easy to install Nice coating and welded between flanges all in a 3 piece. Sure will last for a long time. Truck runs smoother and doesn't feel laggy at all had to remove some pre boost to tone her down a bit. Thanks DPS just what I needed .
Perfect! 5

sounds like new truck at 305k...mine shrank badly on ends, does make my 66mm turbo sing 2-300 rpms earlier and the top end it loud n pulls hard but also has light pedal power too
