I had bought a full titanium exhaust and PCV from a member here a while back. I got them installed along with a new K&N air filter and did a flyectomy. The member I got the PCV for said it was the same setup as his bike with his map. I ran it a couple weeks and it was definitely stronger than stock. Today I finally had time to get it in the shop to be sure the map I had wasn't too out of wack. They showed me the first few pulls all around the 124hp range. The AFR looked real good, right around 12.5-13. They ran it a bunch after these first pulls. They have a big window where you can watch it being done. I know they were in there over two hours running it and tweaking on the PCV settings. After they were all done, the gave me the sheets. They ended up at 147hp @ 9200. The thing I don't really understand is that the AFRs are essentially unchanged. Were they making other changes that don't show on the sheet or something? If the AFRs don't change, where did the boost in HP come from? Did they just play dyno games to make it look like they really tweaked it in but in reality did nothing for it?
At this point, I'm wondering if they were just blowing smoke up my ass!
