I just got back from a test drive, however, it was raining (If you can even call it that, but wet enough to ran in 4Auto to keep traction) and there were lots of needlessly slow idiots about(Around here they seem to think the sky is failing and do 30+ under when they see the tinniest amount of water). I will have to do some more testing when its dry and the roads are less crowded, but I'll give some impressions anyways. I would not stack the Pulsar with the PC unless you want a super super touchy throttle or you like the weaker modes (2-4). Honestly Levels 3, 4, 5, and 7 are pointless (Eco mode is trash and MDS in a perf mode is stupid imo), however, level 6 is about the pedal response I get out of my Scat Pack in normal mode while level 8 is somewhat close to the pedal response I get out of the Scat Pack in sport mode(Just a bit touchy). I'm pretty pleased as I now longer have to manually kill MDS (I will only be using levels 6 and 8), the truck does pull a little harder, and I can re-purpose the PC. Currently my truck has the following mods and I only run Shell 93 : Vararam, Moes 87mm TB, BT Catchcan, 190 T-Stat, V6 efan, most shutters removed, and a Flowmaster Super 10 direct fit muffler. Is it as good as a PCM swap custom tune and a TCM flash ? Not at all, but it is better than stock + PC and it's easy to revert without a trace should I need to use my lifetime warranty.
