Ok so I installed a ATS manifold and a SPS 62 on my 04. 5 and now I am burining what i am assuming is oil. Running down the highway don't notice anything but when i pull off an exit ramp and stop the smoke starts rolling out the exhaust, and smokes at low speeds/idle. Didn't have this problem before this stuff went on. I run Amsoil 15w40 synthetic which was just changer about a 1500 miles ago. Any help would be greatly appriciated. Only other mods right now are Banks Techni cooler, Afe Stage 2 intake, and MBRP 4" exhaust. Truck has about 49k miles on the clock. No programmers or downloaders on the truck as it sits. Don't seem to be loosing any coolant, and don't have gauges since i took the Edge box off. Haven't had a chance to replace it yet. Edge has been off for over a month.
